Ubuntu Networking :: VPN Connection Between Two LANs

Feb 18, 2010

Have you ever created a VPN connection between two LANs which are geographically far away? For example LAN1 is and LAN2 is If I am in LAN1 I would like to be able to ping and get packets back.

I am trying to do it with OpenVPN. I can connect two computers from both LANs using their virtual IP but I can't do that with their private IP. I think the solution must be in creating a bridge or using the "push" command of OpenVPN, unfortunately I haven't found clear information within the internet.

Networking :: Setting Up Two Different LANs Using Three Routers?

Jun 14, 2010

So I have 3 home routers, 1 belkin and 2 netgear. I have my ISP internet connection coming into my belkin, which I then have the 2 netgear routers (from their WAN) plugged into Belkins LAN ports. Now the Ubuntu computers I have on Netgear LAN 1 and Netgear LAN2 can get to Belkin just fine (at, but I am unable to access a computer on LAN1 from a computer on LAN2 and vice-versa. My Belkin is, my Netgear1 WAN is and Netgear2 WAN is I have the netgears both assigning DHCP IP's from range of to on their LAN ports.

Now, I have set Netgear LAN1 port 80 NAT'd to go to one of my computers on it. I try to access from a computer on Netgear LAN2 network and it say host unreachable.What am I doing wrong?

Networking :: OpenVPN - Different Subnets For Physical And Virtual LANs?

Jan 27, 2010

I have set up OpenVPN server using a bridged configuration. My networking "powers" aren't that advanced, so I did this by following the openvpn tutorial for bridged servers. I have tested this with several clients connecting to my server from different locations and it works very nicely (including broadcasts).

My server's LAN IP address is, and my LAN's mask is 24. Clients connecting to my server get assigned IP address that also fall within that subnet (i.e., the 192.168.2.x pool contains both physical machines in my home and "virtual" hosts). This is what the OpenVPN walkthrough specifies:


I was wondering if it would be possible for the VPN to fall within a different subnet (such as 10.0.1.x). I would also like to do that without adding another physical NIC to my server, or changing my physical IP address. I would imagine this is possible, since that's how hamachi does it.

Networking :: Static Routes Between Two LANS Each With Their Own ADSL Line Out

Sep 4, 2010

GNU/Linux gods, guides and superbrains.Don't be moddest. I'ts YOU i'm taking about!I'll be your humble problem-describer-pixie / solution-testing-smerf :

Andreas Vinther, 1977, from Denmark

I'm trying to establish a connection between two seperate ADSL LANs (coming into the house, but from separate ISPs) to a situation where all hosts on either LAN will be able to reach any host on eiher LAN WITHOUT having to use an excess of plastic routers around the house, and please no Wireless bridges. WiFi will only be available as Access Points.

I've heard that Debian does this kind of static routintg / RIP stuff quite well. And I just happen to have one lined up in the right place, that haven't got at snowballs chance in hell of running WINXP or above. But it kills at textbased datamanipulation/forwarding/rerouting/dropping/scanning ... so I'vew made up my mind. That is what I want to do... Now how do io get around doing stuff like that.

The Debian box is connected to both networks: Hostname: AsusAnd
( - TDC network)
and to
( - Profiber network)

Needless to say, but both netmasks are hence the /24 The respective router's LAN addresses are and My Debian are locked to the following IP's (reserved DHCP):

eth0: via DHCP from
eth1: via DHCP from

So far so good - Now here we go ! This is not a scenario where i'd like to always want all network-packages to travel the shortest path, nor NESSESARILY use the other ISPs gateway if the first is down or slow, although that'll be super nice.

I suspect that'll involve router-protocols like RIP. I'll be super pleased to get some guidelines there as well, as i suspect it'll be quite easy to implement once everything else is in place. Although RIP isn't our main goal, it probably comes as a close second. I think we all would like as stable and fast a connection as possible.

I was actually so naive that i thought if i added two static routes to the two routers x.x.1.1 and x.x.15.1, that my problems would automatically be solved by my Debian box, and that it would automatically act as a gateway when the routers send their packages for the other net. As long as i was connected to both LANs at the same time.

Note: I haven't changed or tweaked the Debian kernel to do routing. this is a simple stable install from the net-inst.iso of Debian 5. I'd like to keep it that way unless there's no way around it.

my routers have static routes to each other (WITH PROPER CABLING), configured as follows:

(On router with LAN
[static route] to with nmask going throuhg gateway ( Taken from above info ) - metric around 2
Similary on my other NIC directly cabled to another switch ---and-then-to-another---> Router

Networking :: Using Iptables To Route/forward To Identical LANs?

Jul 18, 2011

The goal is to make connection calls (ssh, ping, ...) possible from one LAN (LAN-1) to a number of (at the moment two) separate smaller LANs.These smaller LANs (LAN-2a, LAN-2b, ...) have exact same specifications (same IP range, same number of nodes, ...)!The idea is to use a Fedora box (release 14 with and implement an appropriate iptables routing/forwarding.The Fedora box has three network interfaces:

- eth0 (aaa.bbb.ccc.m) on LAN-1 (aaa.bbb.ccc.0/24)
- eth1 (ddd.eee.fff.n) on LAN-2a (ddd.eee.fff.0/27)
- eth2 (ddd.eee.fff.p) on LAN-2b (ddd.eee.fff.0/27)

Ubuntu Networking :: Share Files Across Separate LANS Using 2 Routers

Dec 22, 2010

I have 2 routers, each are assigning IP with DHCP on. One router is plugged into cable modem second router is downstairs plugged into first router. Wire runs in WAN of second router. Each router has its own IP subset. First router assigns IP's to second router IP's to

I know I can use the second router as an AP with DHCP OFF. BIG BUT though is my wifi verizon phone got no IP assigned when running like that and wirelessly connecting to the second router. Laptops were just fine. SO, I reconfigured second router with its own subset IP being handed out. Now verizon phone is perfect.

How can I share files between connected PC's using it this way?

Networking :: Configuring Multiple Separate LANs In Same Physical Network

Jun 27, 2010

For some simulation, I am trying to configure a setup of 3 ubuntu desktops (one of them with multiple network cards) to behave in the following way:

Each one of them should be a separate network not seeing the others (including multicast addresses) They need to have internet access through the machine with multiple network cards. So from the point of view of each machine they define a LAN in which it is the only device and have internet access through the gateway machine.

What do I need to do to configure these machines for the above setup?

Ubuntu Networking :: Wireless - Lost It - 'wmaster0 No Wireless Extensions', But Then Refers To Wlan0 As The Wireless Connection

Mar 28, 2010

A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.

Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:

1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.

2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).

3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.

OpenSUSE Wireless :: 11.3 - Can't Set Up Wireless / Wireless Card Is Not Being Used?

Jul 17, 2010

Want to eventually make the switch over but figure taking it slow and learning on an old laptop would be best.

I went through the installer and everything looks great so far except I can't for the life of me seem to be able to get the wireless working. I tried everything a windows newb like me could think of ... it looks like to me the wireless card is not being used since it can't detect anything? I read some threads and here are the results of common terminal stuff that most people say to do:

General :: Wireless Puppy On An Old IBM T30?

Mar 2, 2010

I'm fairly new to linux, I can't get puppy to connect to ANY wireless network, protected or not. The driver autodetected my wireless card (IBM high rate wireless LAN with modem II) as an Intersil Prism 2.5 chipset, but it will not work. I wonder if the driver is corrupted, or if I should just use ndiswrapper with the windows drivers. Obviously, I would prefer to use native linux drivers, but the wrapper will not tax the system too much if I use that option. I have heard that these laptops are very linux friendly, and I ran xubuntu on it for quite some time with no big problems. My home router is a Belkin F6D4230-4 V3. This thing will not show up at all, but my family's old linksys will, I can't connect to it either.

General :: Wireless Router Can't Be Found?

Jul 27, 2010

I have a very strange problem with my wireless routers, or linux. I have 2 wireless routers one directly connected to my modem (router 1) and another wireless router (router 2) on the 2nd floor connected to router 1 without cables and configured as a repeater bridge. Router 1 is configured to broadcast the ssid and have been set up to use wpa-personal and router 2 has the same configuration as router 1 plus a virtual interface.

I am able to connect to both routers from all my windows boxes, but I fail to connect from linux (I have tried with 2 different laptops without luck). What is very strange is that I can't see the routers when I scan but I am able to see my neighbors routers. I have tried to turn off router 2 to see if it had an impact, but no luck. I know that I am able to connect to a wireless router since I have had success with that at work.Router 1 is a Siemens se551 (with default firmware) and router 2 is a linksys wrt54g (running DD-WRT build 13064).

General :: Multiple USB Wireless Devices?

Aug 25, 2010

I have a broadcom wireless card in my laptop and as far as I know, it acts as an USB device. I also have one USB stick wireless device (TL-WN422G - uses ath9k_htc driver) which I want to use at the same time as the first (Broadcom) device.

The problem is, after I load ath9k_htc - iwconfig does not show the new USB device (the TL-WN422G - wlan1 / ath0 / whatever), but only the old one (wlan0 - Broadcom, checked by MAC).

I tried this USB device (TL-WN422G) on my other computer that has PCI wireless card in it, and they both worked just fine together after I pluged it in... I get wlan0 (Ralink) and wlan1 (TL-WN422G). Is it some kind of a problem for the laptop that both devices are recognized as USB? How do I make wlan1 appear on my laptop?

also, my system is fully up to date 2.6.35 kernel (Arch)

edit: I've already downloaded the needed ar9271.fw from and I put it into /lib/firmware - something wrong in that?

dmesg gives me this on laptop:

usb 1-5: new high speed USB device using ehci_hcd and address 9
usb 1-5: ath9k_htc: Firmware - ar9271.fw not found
