Ubuntu Networking :: Bridging Internet Connections And OpenVPN?
Jul 13, 2011
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
10.8.0.2 * 255.255.255.255 UH 0 0 0 tun0
XXX.XXX.XXX.0 * 255.255.255.128 U 0 0 0 eth0
10.8.0.0 10.8.0.2 255.255.255.0 UG 0 0 0 tun0
default XXX.XXX.XXX.1 0.0.0.0 UG 100 0 0 eth0
How should I be configuring this so that when I'm in the VPN I can get through to the internet?
I only have very basic understanding on how it works.This question may have been asked so many times, and honestly I've tried so many tutorials and have read a lot of articles but it all didn't worked. I may be too stupid to have this done, or it is just the lack of knowledge.
Here it goes,I have a VPS with a host which runs OpenVZ in LA. I want to create a VPN tunnel to the VPS and tunnel all my internet traffic to the VPS. Can somebody please help me out on the step-by-step?
I was once able to configure the VPS to run OpenVPN and my client pc was able to connect to it, but the internet connection is still thru with my local connection. Did it with a tutorial too. I would also like to ask, The VPS has 512mb of RAM, I was wondering how many clients can it handle at the same time.
I know my way around windows but my Vista files got corrupted a few days ago and thats why i decided to use Ubuntu.Well anyway, this is my problem.Ive got a Acer5920 Laptop and an Xbox. My xbox is in the living room and Id like to connect it to the internet. When i had vista i used bridged connection. :Xbox => ethernet port of my laptop bridged with wlan of laptop => router.Bridging connections on vista is fairly easy but I have no clue how to bridge connections on ubuntu.
I'd like to configure IPtables to make sure I can only access the internet through an openvpn connection (so when the connection is down I have no way to access the internet but to connect to the vpn again).
I know how to do this with Firestarter (restrictive outgoing policy and I only allow the vpn server IPs) but Firestarter seems to be stupid : for some reason eth0 was changed to eth1 and Firestarter can't work properly anymore, even though that probably can be fixed with Firestarter I'm no more interested in this program and I'd better like to know how to apply the same policy using IPtables.
I've tried a few things already but it failed each time ... how can I effectively allow my computer to connect to the VPN while everything else is blocked ?
Just curious to see what everyone's opinion on using routing vs. bridging for openVPN. I'm installing openVPN on a linux box that I'm using as a router. What I was wondering was your opinions on which one of these two options to use.
I'm currently trying to set up OpenVPN on my Ubuntu Server, however I'm having trouble setting up bridging. I am following the tutorial for bridging that is located on the Wiki here: [URL] At the current time my /etc/network/interfaces looks like this (default from Ubuntu install):
I've been trying to access the internet on my desktop running 10.4 x64 through my laptop running windows XP. The laptop has a wireless connection and I'm trying to use an ethernet cable to bridge the connections. I've hooked them both up, and under Network Connections in XP I selected my wireless connection and the 1394 connection and right-clicked to bridge, and it does. But ubuntu doesn't want to pick it up.
I dont know if its possible or not ? I'm using 3G dongle (ppp0 interface) for connecting to internet on my laptop running ubuntu 11.04 , now i want to share this 3G connection to my wireless router(Trendnet TEW-652BRP) through eth0 interface in simple my connection should be like this
INTERNET<<<3G WIRELESS MODEM<<<LAPTOP----WIRED CONNECTION TO WIRELESS ROUTER<<<OTHER DEVICES (LIKE ANDROID MOBILE/LAPTOPS SHOULD CONNECT THROUGH THIS WI-FI CONNECTION)
My roommate has a slow ADSL provider, and i have a much faster cable connection. He has his own residential gateway, and as do i. The goal i am trying to accomplish is to share 2 printers (1 behind each residential gateway) and also files between computers on the different LAN segments, but not share ISPs or DHCP servers.
Thus far, i have configured my residential gateway's DHCP server to have control of the 192.168.1.0/24 network and his gateway's DHCP server controls the 192.168.0.0/24 network. We've got a Slackware 13.0 Linux box connected on the 192.168.0.0/24 network which currently just serves a web page and accepts e-mail for a domain. My knowledge of networking fails me here as I'm not sure what piece of equipment i would need to buy to solve this puzzle (bridge or router). I know iproute2 can do wonderful things on Linux, and i figure it would be easier to just shove a NIC or 2 in the Linux box and make it do what i need instead of buying more networking equipment.
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 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.
Is there any way to get drivers working? My hardware switch is on and i have Ubuntu 9.10 running persistently on my usb so i can download the drivers etc. and install them.
I am a user of Ubuntu 10.04 and I use Firestarter because it lets me know which IPs I am connected to, which ports are used, and which applications are using those ports. The problem is that I can't use Firestarter with my non-sudo account (well, I know that I can change my system settings to do that, but I'd rahther not do it).
So the question is: Is there any application that lets the user monitor the internet connection?
I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.
I've got a Ubuntu Server Linux router that I've got 2 internet connections hooked to. One of them is DSL and the other is cable.
What I'd like to do is have everything go through the DSL connection EXCEPT for one desktop, I'd like that system to go through cable for everything.
Here's a diagram of how I've got things set up.
[URL]
I don't have any more expansion slots on the mainboard of my server for another NIC, also I do a lot of file transferring between a laptop and the desktop I want on the cable connection so I don't want that slowing down the rest of my network.
I've got both providers set up in the providers file and I've got everything going through the DSL connection right now. So far everything I've tried has stopped the desktop from connecting out at all.
While using Ubuntu two other computers lose their connection. One (main) is connected to the modem, other from the switch to the wireless router, and the one with ubuntu wired via switch. Currently connected with Windows 7, other two are connected. Once booted into Ubuntu rest of the computers disconnect?
I Installed Ubuntu which was on the laptop before and this install doesn't want to work with a Internet connection. I know my connections is good and the Laptop is fine because it used to have dual boot and windows connected fine.
I have a question, regarding the use of two internet connection on the same server. So, the thing is like this: The server will have 3 network adapters: connected to a DSL modem (on this adapter I have one of the internet connections, a PPPoE connection. It's only purpose is to share the internet connection to all LAN users using SNAT.
eth1 ----> the other internet connection, a much more expensive one actually, used for hosting a website, a domain name server, and a qmail server. eth2 ----> LAN connection So what I want is to make eth1 the "default gateway" (for outgoing mail, DNS requests, etc) and, as I said, use the ppp0 connection on eth0 only for internet sharing in LAN.
My question is (since I'l configure this server in about one week), does anybody have any suggestions regarding how could I accomplish this? I mean, I'm affraid that ppp0 will also try to use the default gateway from the other internet connection and vice-versa. Now, I know I can use the ip route/ip rule commands, but for many reasons I'd like to keep it simple and not use them.
I have two internet connections. One is wired ADSL Broadband & another is USB EVDO modem. I can use only one source at a time. That means the traffic will pass through either ADSL or EVDO. Other connection just sits idle. I want to use both the connections together so that I will have increased bandwidth. Is there a way to do that?
My computer has one NIC card. Both ADSL & EVDO use dynamic IPs.
I have a firewall ( a pc with debian 5) with 2 internet connections. each connected to a ethernet card (the firewall has 2 ethernet pci cards so it has one connection per card)how can i balance the internet requests from my LAN using this 2 connections?
I have to configure squid server which will have two internet connections on two separate lan cards and both will run simultaneously.I know how to configure squid server with one internet connection
I'm running ubuntu lucid and i was thinking in purchasing one or more extra wifi cards to try to configure my computer to manage different conections at the same time, with different isp's. The thing is that I'm not quite sure if what i want to do is actually possible.
The easiest way that crossed my mind was to try to configure a / multiple virtual machines that are redirected threw proxies to ubuntu and try to configure that each proxie port goes threw a different internet gateaway. This way i might be able to divide threw different sessions of JDownloader, installed on each virtual machine, the things i want to download. The negative aspect of this idea is having multiple jdownloader sessions will make my laptop work to almost 100% for sure...
Another thought i have was to make JDownloader manage its downloads in only one session redirecting them to my internet conections; the negative thing is that i think i will have to try to modify its source and learn java...
And well my last possible configuration i had in mind was to try to make ubuntu directly add up all my internet conections manage as if it was one. the negative thing here is that i might not be able to get multiple downloads from some sites
Well, all this where just thoughts, im struggling whether to buy another card or not to try to setup any of this configurations but im not really sure if any of them are actually possible. Is there an easy way to manage this?
I just want to take the most out of my internet conections... if i'm at college i have to options that are quite slow, adding them up with two cards would be great, i might also be able to add a third and a fourth conection. Also if i'm on a coffe and i need some bandwith i could try to make it go with an open network arround, etc.
Can I bind 2 interent connections or more on same fedora server to create bigger one with double bandwidth ,or it needs a specific router to be able to do this.
I have seen several threads lately about slow internet connections here and elsewhere, but I haven't seen anyone post a reply about blacklisting ipv6 so I am curious as to why?Is ipv6 enabled only on certain distro's or is there some other reason that it's not mentioned?
<If anyone wants to try it, to see if it would work for them>
On Slackware 12.2 and Salix 13.0 just add "blacklist ipv6" to the /etc/modprobe.d/blacklist file. I'm not sure about non-slackware based distro's. Unfortunately, I don't know any way of doing it without rebooting.
My problem is that I would like to load balance or aggregate 2 separate Internet connections on my laptop. Currently a hard line ISP is not available so I'm using an Sierra Wireless 885 USB air card. Thing is the card is quite slow. I also can tether an iPhone to the laptop. The ideal solution would be to have both connections being utilized to help speed up the overall experience, even if it is only a modest gain in speed.
as I do not know much about iptables and basic TCP/IP routing, I'm finding it difficult to implement those solutions. If someone can point me in the right direction ( a slightly dumb down how:to? or better explained? )
BTW, both phone and aircard get dynamic IP's. Running Ubuntu 10.4
i have some problems with configuring openvpn tunnel connection to my openvpn server. I'm using static-key tcp connection. Network manager always said to me that connection could not be established. Also, when i try to run openvpn from terminal, i got some strange permissions problem:
Code:
openvpn --config config.ovpn Mon Apr 5 15:48:37 2010 OpenVPN 2.1_rc19 i486-pc-linux-gnu [SSL] [LZO2] [EPOLL] [PKCS11] built on Oct 13 2009 Mon Apr 5 15:48:37 2010 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables Mon Apr 5 15:48:37 2010 /usr/sbin/openvpn-vulnkey -q moj.key
My linux box has 3 network adapter. eth0 connects with ISP, eth1 is for staff network, eth2 is for public user. I want to limit the usage of internet bandwidth. for example, the traffic going through eth0, 75% is for staff network, 25% is for public user.In addition, I setup shorewall on it for port forwarding and filtering, but I felt the traffic shaping of shorewall is complex. I don't need the specific TOS, but only the percentage. could you give me some suggestion?Which software or package I should use to achieve this goal?
Here's the story running 10.10 on my box with a wireless N adapter I'm about to go get a XBox with the built in wireless but the problem is that the XBox does not pick up 5ghz. Any way to connect the XBox with a ethernet cable to my motherboard and bridge those connections so the XBox can get network access?
My laptop, which is my main machine, is running Ubuntu 10.10 I am bridging my wireless connection on my laptop to my Dell desktop; but I have somewhat of an issue. I was able to bridge the connection with ease, but the IP the XP machine has been assigned is not in my subnet. The issue is that I need to port forward to this machine, but my router doesn't recognize that the PC is on the network because it has a random IP. I've tried assigning a static IP on the XP machine itself, but it doesn't change...
I have a Dell Studio 1501 Laptop and I want to bridge the wireless with the ethernet port so I can hook my xbox360 to my laptop.
I've spent the last 2 hours trying different techniques but nothing is working.
I'm running Ubuntu 9.10 so the last thing I tried was going into the network manager, clicking on wired, editing the ethernet port and allowing it to share. This did nothing.
I tried to share the connect with firestarter but that did not work either.
