I have some questions about openVPN. I am wanting to hide my downloading through transmission and I'd like to know if I can use openVPN for this? Also do I need access to a server? I don't understand how it all works.
View 5 RepliesFirst post on this forum and feel a bit bad for asking a question but would really appreciate it if you guys helped out. I have been using Linux for a while now and it has become my main OS and I'm looking to purchase a VPS or Dedicated server to play around with as im starting a computer science course soon. I was wondering if anybody in this forum would guide me to any guides on setting up a VPN on the dedicated/VPS server so that I can create an account and use it to encrypt my traffic and change my IP, I have looked around for a while and have only found info on connecting to another computer through VPN to use there network and applications but I don't think that is the type of VPN I'm looking for.
View 4 Replies View RelatedI 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.
View 2 Replies View RelatedI 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:

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
View 7 Replies View RelatedI 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

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)

SSH uses a keypair to encrypt traffic between the host and client. Which key is stored by the client ?
View 2 Replies View RelatedWe have something on our network that is reaking havoc with our content filter. I am trying to track it down, but so far I have been unsuccessful. We have approximately 500 devices in 100+ different locations spread across 9 states. Looking at each computer is not really feasible.
I need a machine that can sit in between our network and our internet connection and graphically monitor in real time and logs how much traffic each device is sending and receiving. It would need to sit inline so it has to have two nics and be able to pass traffic. The machine also needs to be transparent. Reconfiguration of our routers or workstations is not an option.
I have used ethereal and wireshark before. Ethereal may be a viable option, but wireshark seems to provide lots of information, but no practical way to make use of it. how to set up the box to be a transparent device on the network that will allow internet bound traffic to flow (freely)?
I'm playing with OpenVPN and I'm trying to share my VM's internet connection with another VM. My server VM has internet access through a NAT interface on virtualbox. My client can even ssh to the server, so the openvpn tunnel must be working. I've tried on the server:

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 &

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.
I am sharing my DSL internet connection using a modem+wireless router (single device) to 5 systems. I want all my internet traffic to go through one of the linux boxes in my network.
The problem here is that wireless devices connect directly to the modem+wireless router.
Is such routing of traffic possible??
PS: I am not sure if i could convey my situation clearly...
I'm trying to set up an openVPN server for a small office. I've gotten the server running, and configured keys, and been able to connect to the server. The trouble is that once I connect with my windows machine to the server, I am unable to bridge through to the www. I have combed through so many settings and tutorials, and I am confused as to how to set up the interfaces configuration file. Here's a sample of my routing table:
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface

How should I be configuring this so that when I'm in the VPN I can get through to the internet?
Is there a nice easy to use tool that displays (in KB/s) the internet traffic from every IP on a network?
Currently I'm using iptraf, but it's very hard to understand at times.
A little info on my network:
I'm using SNAT for internet sharing.
My PC is part of a LAN so while configuring eth0, we specify the Gateway to access all other resources in the network. The PC successfully access Internet through a proxy server configured in Mozilla(manual proxy config) but the update option or the Synaptic Pkg mngr are not able to access internet anyway. I have tried the option "Apply System Wide" in "Network Proxy" but no progress so far.
I also tried to forward all request coming for udp/tcp on port 80 to the proxyserver on a specific port, but with no success. Also I can't ping any website from terminal, reiterating the fact that I can access internet in firefox through the proxy on a specific port.
My ISP has given me 3 IP addresses to use for the internet (76.148.200.3, 76.148.200.4 and 76.148.200.5).
If I do a "wget whatismyip.com" or netcat into another server, I am appearing as 76.148.200.3.How do I change my route (command line) in linux to route internet traffic through 76.148.200.5?

I have eth0 and tun0. tun0 is a VPN tunnel going over eth0. Everything on the other end is setup and working fine, when I type Code: traceroute 4.2.2.1 I see my the ping is going over 192.168.2.99 (eth0). When I then type Code: route add -net 4.2.2.1 netmask 255.255.255.255 dev tun0 traceroute 4.2.2.1 I see ping is going over 10.8.0.1 (tun0) instead of eth0, so that is working
What does not work however is when I do Code: route add -net 0.0.0.0 netmask 0.0.0.0 dev tun0 traceroute 4.2.2.1 I get no ping! I believe the problem is because all traffic is routing over tun0, which means even the VPN tun0 needs to go through eth0, it can no longer do this. Is there a way around this where I can route everything except for 114.77.31.26 (which is my VPN gateway for tun0)?
I'd like to allocate a certain quota to my local user for their internet navigation.
View 8 Replies View RelatedI 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?

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?
I have a 2 machine LAN with both machines having an ethernet card and a wireless card. There is a Netgear router, both eth and WiFi, allowing both machines to access the internet.
On my Linux machine I am looking for some software that allows me to keep track of my broadband usage on that machine, excluding traffic between the two machines.
There are numerous such programmes for this in XP, which use Winpcap and a GUI frontend. The "other" machine on my LAN is XP and uses just such a program.
I have a desktop, a laptop, & a wireless router. The router, unfortunately, doesn't support dd-wrt, tomato, etc firmware, but I would still like to prioritize voip/web browsing over bulk Internet traffic. I hope I can offload the router's missing QoS to my desktop.
Is it possible to have the laptop's connection go from the wall to the router to the desktop, where the desktop could perform the QoS of tomato, then continue on to the laptop? I'm a bit of a noob to networking (subnets?) but do well enough following good instructions.
As for the program that would do the QoS... Don't some Linux machines basically work as super-powered routers for businesses? So there must be some package but couldn't find one. The closest I got was wondershaper but it only shapes traffic for the computer on which it's installed; it might form part of the solution but falls short on its own. other devices should be able to access the Internet normally if the desktop is turned off, & work with other devices like a (jailbroken) iPod Touch.
I have the standard wired LAN NIC and a wireless NIC installed. What my problem is, the wireless NIC will not take any internet traffic. The LAN connection gets it's internet from my LAPTOP with a Clear 4G module. I have a very strong wireless connection, but when I remove the LAPTOP from the network, I get nothing on my Ubuntu computer here, even though I have a solid connection. What is needed in the config to let the wireless run in the "back up" internet connection mode?
View 9 Replies View RelatedMy internet gateway is 192.168.1.1 with a 255.255.255.0 subnet mask. I have a router connected to it running ddwrt with an ip 192.168.2.1/24 creating a second subnet behind it. I have a tenant moving in that will be wirelessly connecting to the ddwrt router, so to the 192.168.2.0/24 subnet. What I am looking for is a rule that will pass internet traffic to and from this client, but restrict him access from the 192.168.1.0/24 subnet otherwise. The ddwrt router is connected to the 192.168.1.1 gateway through its wan port, btw. For example, the client would get an ip address of 192.168.2.100 wirelessly from the ddwrt router. I want him to be able to surf the internet through the 192.168.1.1 gateway, but not to have any other access to the 192.168.1.0/24 subnet (ideally not have access to ANYTHING besides the internet).
View 4 Replies View RelatedI 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..

I need to set up my centOS computer as a firewall in my home network. Ive got 2 interfaces, eth0 and eth1. I want to allow and forward all traffic on eth0 and block all traffic on eth1 except ssh, ping(icmp) and DNS. How do I do this? Ive tried some editing in /etc/sysconfig/iptables but no luck.
View 1 Replies View RelatedI 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

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