Networking :: OpenVPN Connects But There Is No Traffic?

Dec 10, 2010

I have installed OpenVPN to use it as an internet gateway butcan't get it to work.OpenVPN installed without any problem. The client can also connect and ping the server but there is no internet traffic.I think it is because of a wrong gateway address which the client gets but I'm not sure. server IP address is 10.8.0.1 and the client can ping this IP but it's default gateway is always 10.8.0.5 which is not accessible from the client.This is my server.conf:

Code:
dev tun
proto tcp

Networking :: OpenVPN Connects But No Replies To Pings

Jan 7, 2011

I have an asus router running tomato firmware. Through the webGUI I have set up an openVPN server as per the tomato guides. I am using the network manager plug-in in ubuntu 10.04 to connect as a client to the tomato openVPN. All of my certificates seem to be set up and working correctly.

I am able to successfully connect to the openVPN server using the ubuntu client but after that I get nothing. On the client side I am unable to ping the router, any ip addresses inside my private network, the virtual network ip, and web browsing (client) no longer works.

Also, when connected I am unable to ping the client from the private network.

Before connecting

Code:
chris@ChrisLaptop:~$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:1e:68:90:5e:e9
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

Ubuntu Networking :: OpenVPN For Some Traffic, But Not All?

Mar 1, 2011

I have access to a VPN I use when having confidential instant messaging sessions. For the purposes of my work, essentially.I'm a command line kind of guy, and like to use Finch (the shell version of Pidgin) for those.However, when I turn on my OpenVPN connection it routes all traffic through the VPN. Web-browsing, IMing, and I can no longer access other machines on my home network.Can I set OpenVPN to only route traffic I ask through that connection (either by port number or application, or some way I haven't thought of), while other traffic flows through my usual home network?Some kind of local proxy perhaps? Or a dd-wrt box set up as a proxy, connected to OpenVPN?I've played around with the GUI environment too (I have a basic GUI I sometimes use on my main machine) and have installed the full desktop 10.10 on a second machine just to see if I can work it out.

Ubuntu Networking :: OpenVPN Works, But No Traffic?

Aug 31, 2010

I'm facing a problem when I establish VPN connections using OpenVPN to Your Freedom Server. " you can see their documentation here ", I've installed OpenVPN from synaptic and I used the client to connect through VPN and it works !! but there is no traffic in FF or any application !!I tired to insert some HTTP proxy also belongs to the same server and it works. What really wonders me is that OpenVPN seems to work only when I'm connecting to streams sites "e.g. ustream, justin.tv" Is there anyway to force the whole traffic to use OpenVPN " I'm using Mobile modem and it works fine with OpenVPN in win7

Ubuntu Networking :: NetworkManager Redirecting All Traffic Over OpenVPN?

Jan 16, 2011

I got it set up in the NetworkManager applet (imported the client.ovpn), but when I connect it sends ALL my traffic through the VPN. I would prefer all accesses to the internet go over my normal default gateway, rather then all the way through to the VPN's default gateway.When I connect through the command line:

Code:
openvpn --config client.ovpn
I don't have this problem, and accesses to the internet still go over my default gateway on

Ubuntu Networking :: OpenVPN Works Fine, But Can't Filter Traffic Between Users?

May 13, 2011

I'm using ubuntu server 10.04 with openvpn installed on it. My vpn is working fine, all the users can connect without any issue.My problem is that I'm unable to filter the VPN traffic using openvpn. I can't allow all users to be able to interact with other vpn users. I need to avoid this kind of traffic.I was trying to build an iptables firewall, but I just noticed that my openvpn traffic isn't being filtered by iptables.In FORWARD chain, no matter what rule I use openvpn would continue to allow traffic between my clients. It does appear that openvpn is skipping FORWARD chain?For example:

Code:
# iptables -L FORWARD -nv
Chain FORWARD (policy DROP 0 packets, 0 bytes)

Ubuntu Security :: OpenVPN Connects To VPN But No Internet (10.10 64-bit)

Jan 5, 2011

I use vpntunnel.se and followed their tutorial for OpenVPN and it connects and assigns an IP. However, once the sequence is initiated and I open my browser I cannot connect to a webpage and get a "cannot resolve" error. I e-mailed their support and they suggested I change the DNS of my network settings. I did that but the same problem. Once I close OpenVPN my internet works again. It works in windows, so I know it is not my router...I use a wireless connection with my router. I don't know if this has something to do with anything...

Slackware :: Connecting To Openvpn Server - Connects But Fails

Jul 18, 2010

I've configured an openvpn server on a wrt54g using dd-wrt firmware. I can connect from the command line...at least it appears to connect, but I am unable to access any resources. Trying to use networkmanager's openvpn client fails every time. Everything I find googling relates to Ubuntu, so just for kicks I booted into my Ubuntu partition for the first time in months....and the wireless lan disappeared when I restarted network manager, which is why I don't use Ubuntu in the first place, so much for the "easier distros". I'm assuming there are people successfully connecting to openvpn servers from Slack. I could definitely use a pointer.

Debian Configuration :: Traffic Bypasses OpenVPN

Sep 16, 2015

I'm running OpenVPN service on both debian server and client. When start connection between client and server, I expect all the computer traffic (except ARP and DHCP requests) go through created tunnel. However, when I capture packets on wlan0 on client (the only connection going outside host) using Wireshark, I can see DNS requests visible and sometimes incoming TCP traffic as well, but most of the traffic is going through tunnel as expected. I provide both configurations of client and server and client routing table for inspection. I changed server address to avoid server exploitation in the case of some big configuration mistake.

Commands to run OpenVPN services are:
Code: Select allFor client: sudo openvpn --config /etc/openvpn/client.conf &
For server: sudo openvpn --config /etc/openvpn/server.conf &

**Client routing table when VPN is OFF**
Code: Select allKernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.1.1     0.0.0.0         UG    1024   0        0 wlan0
192.168.1.0     *               255.255.255.0   U     0      0        0 wlan0

[code]...

I searched through many forums and documentation and I found, that for all the traffic going via VPN is command: *push "redirect-gateway def1"* neccessary, however, I have leaks despite this command being in place. I already spent over 2 days with this and tried to configure it in many ways, now I have no clue what I'm missing.

OpenSUSE Network :: SUSEFirewall Blocking OpenVPN Traffic - How Can Configure To Allow

Nov 17, 2010

I have a remote network that I manage consisting of a DLink DFL-210 firewall/router, and behind that a Dell server running openSUSE 11.2 and a collection of Windows XP/Vista/7 computers.

The Linux box is running OpenVPN as a server (that is how I connect to this network) and a client (it connects to a second server - running XP - at a different location).

The DLink router is the DHCP server and provides addresses on the 192.168.51.0/24 network. The OpenVPN server provides the 10.8.51.0/24 address range.

The remote network that the Linux box connects to is 192.168.54.0/24 via the OpenVPN network 10.8.54.0/24.

I have added routes to the DLink router to route all traffic to the 10.8.51.0/24 and 192.168.54.0/24 networks to the Linux box.

With SUSEFirewall turned off, after I have connected via OpenVPN from my remote computer I can ping all active 192.168.51.0/24 addresses. Other computers on the 192.168.51.0/24 network can ping computers on the 192.168.54.0/24 network. But if I turn on SUSEFirewall, neither of these work. However, I can ping 10.8.54.1 from any computer on the 192.168.51.0/24 network.

How can I set up SUSEFirewall to allow these networks to communicate with eachother?

Ubuntu Servers :: Setting Up A Bridge For OpenVPN / Tunnel All The Traffic Through The VPS?

Feb 3, 2011

I have an Ubuntu VPS running 10.10 x86_64

This is what is in my /etc/network/interfaces right now.

Code:
auto eth0
iface eth0 inet static
address 67.202.x.x
gateway 67.202.x.1
netmask 255.255.255.0
auto lo
iface lo inet loopback
My server.conf
code....

I can get the VPN server running and everything connects fine from the client. I just don't know how to tunnel all the traffic through the VPS because it involves making the bridge which I'm having trouble with. What exactly am I supposed to put in /etc/network/interfaces?

General :: Redirect Incoming Traffic To An Other Port (ubuntu Openvpn Server)?

Dec 5, 2010

I have set up an openvpn server on ubuntu via port tcp 443. The server use a public network and almost every ports are blocked (not 443) So when a client connect to the server, if it send traffic needing a blocked port, the connection cannot been etablished of course. So i d like to know if it is possible to redirect all incoming traffic on the server to an other unblocked port (like 443) to bypass firewall.

I dont think openvpn offer this possibility but maybe with linux it is possible..

Networking :: Server To Block All Traffic But US Only Traffic?

Mar 15, 2011

I wanted to tell my server to block all traffic but US only traffic. So i followed this guide:[URL].. Now I know, it's the best way to help prevent hackers/crackers (doesn't matter to me what they are called. I just have to stop them). My server only deals with US clients anyways so might as well just start right there for my server's security before getting into the brute force and injection preventions. So I got it all done compiled everything moved to the proper directory. I then started to setup my iptables. Like so

Code: iptables -F INPUT
iptables -F OUTPUT
iptables -I INPUT 1 -s *.*.*.* -p tcp --dport 22 -j ACCEPT
iptables -I INPUT 2 -s *.*.*.* -p tcp -j ACCEPT

[Code]...

After seeing that i went digging in the code and figured it was something todo with memory allocation.

Server :: PPTP Traffic - Gre Traffic Is Being Generated During The Browsing / Reduce Traffic

Sep 27, 2009

Recently I notice that when I'm connected to an vpn server (pptpd) and I'm using it as a default gateway my download and upload speed decreases almost to the half of the usual speed. I made a test using iptables in order to count how much GRE packets are generated (except the real traffic itself) in that way:

Code:
iptables -I INPUT -p gre -j ACCEPT
iptables -I OUTPUT -p gre -j ACCEPT

iptables -I FORWARD -s 172.16.10.101 -j ACCEPT
iptables -I FORWARD -d 172.16.10.101 -j ACCEPT
The first 2 rules match all GRE packets between the pptpd server and client, and the next rules - the traffic between the server and the client.

When I turn the counters to zero and begin to generate traffic (to browse, to download etc.) I see that the GRE packets are even more than these in the FORWARD chain.

So, my question is first of all is my test correct and is it true that so much gre traffic is being generated during the browsing (it becames clear that the traffic is double than if the pptpd wasn't used as a gateway) and if yes - can that traffic be reduced?

Networking :: Wifi Connects In Windows Not?

Feb 28, 2011

Another issue I'm having, considerably more serious, is my ability to connect to wifi access points with proxies. The story goes, my school has free wifi, but you have to go through their proxies to access the internet (like at McDonald's or Starbucks, where you must 'log in' and accept their usage terms). I can connect, including DHCP, and when I type in any URI I get the redirect posted to Chromium's address bar, but I simply cannot connect to it. This has happened in Ubuntu and Arch, using at least a couple different network management methods (I usually use WICD but I think I started off with networkd). The strange thing (to me) is that my Android phone works just fine, so although I'm not completely familiar with Android on this level, I don't imagine it's the fault of Linux itself. but I'll only be able to experiment with this once a week, on Saturdays (when I have class --gotta do something entertaining).

Fedora Networking :: 8 Freezes When Wireless Connects?

I am using Fedora 8 on my laptop, newly installed, I can see the network card(Linksys WPc54G v2) and Network Manager sees the wireless router, however as soon as I tell it to connect my computer freezes and I have to restart. I searched for solutions but all I found was Ubuntu problems.

Actually it seems that the trigger is when the keyring comes up and asks for a password. As soon as I start typing the pass it locks.

Ubuntu Networking :: Wireless Connects But Can't See The Network

Jan 9, 2010

I've got a Zotac MAG HD-ND01 with XBMC live installed. This is built on Karmic Koala and runs very nicely through the wired NIC.

I configure the box using a cable. I'm using WPA2-PSK and it is clearly authenticating OK.. It gets an IP address.. the AP shows a connection to the box. My XP laptop connects to the access point OK.. just can't connect to the box via the wireless, and it can't see the network using wireless.

I have followed a number of threads on connecting Atheros 9XXX wireless [URL] but no joy.

Also, can Ubuntu connect to the AP at any speed greater than 54MB? My windows PC connects at 144MB+ . Will ndiswrappers connect at those sorts of speeds?

Ubuntu Networking :: Wifi Connects But No Internet / Why Is So?

Nov 23, 2010

Let me start by saying that I am new to ubuntu, and that I always use forums as a last resort.

I installed ubuntu 10, and immediately after the Wifi card deected my network name, and actually connected to it, but then I opened up firefox and....no internet.

Since then I have been trying to fix this problem, and after some research I found out that my card (PCI Cwp-905) is RT2760 based, and I downloaded the linux RT2760 drivers for it.

The driver folder contained a readme file with commands you should enter to install it, and other setup files.
The problem: every command I typed in didn't work. I tried "make", and then "sudo make", but just got permission denied each time. I am now at a dead end. (Please note that I changed my directory to the folder location before doing this)

Does anyone know what I am doing wrong? If you want I can attach the driver files.

Sometimes after 5-10 minutes.When I forse to connect ("Connect to hidden wireless network), the laptop connects after several seconds. But not automatically.My wireless modem uses WPA2, MAC filtering and has a hidden access point.I use Ubuntu 10.4 on a HP Probook laptop. In "Network connections", under "Wireless", the "Connect Automaticly" and "Available to all users" are selected. When connected, the signal strenght is very good.

i noticed today that the last three places ive tried to use wifi at (a friends house, my cousins house, and my moms office wifi) refuse to connect, even after triple checking all the passwords and trying various security protocols (WEP 40, WEP 128, etc.). strangely, last weekend i was able to connect to a hotel wifi signal with no trouble. even stranger, my ipod touch is able to connect to all these places. at my friends house, we even tried an ethernet cable but ubuntu didnt even know it was there. im a little concerned about this, as i might need to connect to wifi for something really important and ubuntu wont cooperate.

Server :: OpenVPN Range Address / When Change Static IP To Dynamic IP In Config File OpenVPN Didn't Work?

Feb 13, 2010

I want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.

So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.

Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.

Well, when I tried to change static IP to dynamic IP (changing '192.168.0.2' to '192.168.0.0/24') in the configuration file, the OpenVPN didn't work.

Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.

I hope I explained my problem as well.

My configuration file:

# OpenVPN Server Configuration File
dev tun 0
ifconfig 192.168.0.1 192.168.0.2
cd /etc/openvpn
secret key_file

In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (192.168.0.0/24, for example), instead of a static IP (192.168.0.2).I also thought to use a DHCP server, but I'm not sure that will work.

Fedora Networking :: Network Manager Connects With 'auto Eth 0'

Jun 23, 2009

I got a little problem with network manager. I got two connections in it, with two different DNS-Servers, because the one of my provider is very slow I surf with opendns, but sometimes that slows down too, so I want to change if necessary. Both connections got the same fixed IP.That worked all fine, until I got my new router (it's a Netgear WGU 624). It's connected by cable and I configured it like the old one. But for some reason instead of connecting to the manually configured connections, my fedora 10 creates a new one "auto eth 0" with a dynamic IP. So every time I boot or switch on from standby my PC connects with this one and I have to manually set it to the right connection. There's no chance to edit or delete it cause those two buttons are grey and won't work. I also tried restarting network manager manually and I also tried starting it with su as root.

Ubuntu Networking :: Edimax 7717un - Connects But No Web Browsing

With manual IP config, ping to my router works fine (and very fast, as does ping to 2 or 3 internet web sites. I can traceroute to internet web sites OK as well. With web browsing, if I wait a few minutes some bits of the page may arrive. With connection set to DHCP, Wicd shows WiFi connecting OK, but DHCP setup times out.

Ubuntu Networking :: Disconnect Pc From Switch It Sometimes Connects Before It Times Out

May 19, 2010

I have my internet connection via a wireless USB adapter and that works fine. Recently I connected my pc (Ubuntu 9.10) through a wired switch to my modified xbox so I can watch my videos in my office. I can share my content with my xbox (except for the items on my external USB HD's - I am working on that and will post that question elsewhere) but when I have my PC's wired connection plugged into the switch I can not surf the web or check email. It gets stuck at resolving host and then times out. If I disconnect the pc from the switch it sometimes connects before it times out. Usually it is quicker if I reboot without the wired intranet connection.

Ubuntu Networking :: RTL8191SE Wireless Connects But Fails?

May 24, 2010

I have a Compaq Presario CQ42-195TX laptop with Ubuntu 10.04 (64-bit) installed on it and fully updated. It has a Realtek RTL8191SE wireless chipset which I am having trouble with - its wired connection is working perfectly.After starting up, I am able to see and connect to wireless networks. Once connected, the wireless functions correctly for a very brief period (under 10 seconds) in which I am able to access the Internet and so forth. The connection then stops working - although it doesn't get disconnected. When I say it "stops working", I mean I can no longer access the Internet and trying to ping the router gives me a "Destination Host Unreachable" error. If I disconnect from the network I cannot reconnect, nor can I connect to any other network.- though I can still see the list of available networks.

I thought that maybe this was a 64-bit issue, but I tried the Ubuntu 10.04 32-bit live CD and experienced the same problem.Please note that while this thread is about the RTL8191SE chipset, the RTL819xSE chipsets all use the same driver.Below are the results of various commands while connected to the network but after the connection has stopped functioning correctly:lspci -nn | grep "Realtek"
