Ubuntu Networking :: How To Bridge Wireless LAN

Jul 30, 2011

I am trying to connect networks connected via locked down wireless routers. Here is the setup:

Internet <-> eth0 - server - eth1 providing DHCP <-> hub <-> wired clients & to WiFi router with NAT & DHCP <-> WiFi clients.

I want the wired clients and the WiFi clients to be able to talk to each other directly, but the locked down WiFi router (meraki) is in the way. the wired clients get their IP address from the server, the wireless clients get theirs from the meraki WiFi router. I can't reconfigure the WiFi router to bridged mode without paying meraki a sizeable annual license fee. What options are out there to get through the WiFi router? I came across OpenVPN and ethernet bridging, but broke networking on the server when trying to configure the br0 interface. I followed these instructions: [URL]

Ubuntu Networking :: Wireless Bridge IP Settings?

Dec 8, 2010

I first want to say that I am very new to Ubuntu so please forgive any ignorance I have successfully given internet access to my xbox by connecting it via crossover cable to my ubuntu 10.04 laptop and given the eth0 settings "share with other computers" My issue is that the ip address being given to the xbox is 10.42.43.10

How can I change this ip address given, or use a static ip address (ie 192.168.x.x) because using this ip address keeps my xbox from accessing windows shares on WORKGROUP on my 192.168.x.x network.

Ubuntu Networking :: Setting Up A Wireless Bridge ?

Oct 18, 2010

I have spent the last 24 hours trying to work a wireless bridge (a D-Link DAP-1522) into my network configuration. It would connect to our gateway here at home (some 2WIRE piece of garbage AT&T hands out, but I digress), and two computers (an Ubuntu Desktop and an Ubuntu Server) would connect via the bridge.

The bridge SEEMS to connect to the router, and indeed, the Ubuntu Desktop PC is able to access the internet. The server, however, is not, and neither computer can communicate with the other (ping, SSH, etc.) furthermore, the router recognizes the presence of these two computers on some level, but does not seem to know their IP addresses (I assume this is related to the computers' inability to communicate).

Before I get too far into this, here are a few links/items for the sake of clarity. The first is a shoddy diagram of my (proposed) network topology, for all of you out there who, like myself, understand things visually:[url]

This is the output from running "ifconfig eth0" on the Ubuntu Desktop PC, which sits behind the bridge. The PC is connected, and can ping hosts across the Internet, but can only ping the router locally (that is, it can't ping any other device in the house, on either side of the bridge):

Code:

The router uses wireless encryption, not MAC addresses, to restrict access/traffic, and all wireless devices (including the bridge) have been provided with the proper credentials. There shouldn't be any devices being denied access on account of their MAC address. In fact, the router's control panel lists the PC and the Server among the recognized devices (even lists their MAC addresses), but provides no IP address and always considers the two computers to be "offline." And yet, I am writing this very post from the Ubuntu PC. Sigh.

I am very comfortable with computers, and reasonably comfortable with Ubuntu/Linux and the Linux command line -- I've been using the operating system for just over a year now -- but networking issues have always been perched right on the edge of my understanding. In short, it's likely this issue has more to do with me than it does with the hardware itself (although the more forums I browse, the more I start to doubt this bridge...).

Ubuntu Networking :: Using Desktop As A Wireless Bridge

Nov 19, 2010

I have a wireless network that is upstairs, i cannot run a cable down here, however i've got 3 boxes that i want to run as servers..

1. Desktop running 10.10 (the one with the wireless card)
2. Server running 9.10 (no wireless card.. is currently connected through a wireless B gaming bridge)
3. An old P4 that I will be putting 9.10 on and running as a server.

Take the Desktop that has the working wireless card as my normal desktop and also running as a passthrough for the switch to go to the other two while still allowing all of the port forwarding to the other two to be handled by the router upstairs so basically what I want to do is this

= wireless connection
- wired connection
[Internet]--[wireless router]==[Desktop]--[switch]--[server1 + server2]

Everything i've come across so far has been for going from a wired router to turn a box into a wireless AP unfortunately i need the reverse.. a wireless bridge. if someone can point me in the right direction (or i'm not against hand holding if it's available.

Ubuntu Networking :: Wireless Bridge No DHCP?

I am trying to configure an external wireless bridge for a few systems to replace a very long, duct taped cable.

I have it set up and it is connecting, at least I can see the pfsense router on the other side and ping any machine in the network.

Here's the issue, I cannot get dhcp to work across the link. I set a static address (dns servers and all) but when I try to ping google i get "Network is Unreachable"

Networking :: How To Set Up Knoppix As Wireless Bridge

Feb 27, 2010

I have a Windows 7 machine which is having issues with a Linksys Rangeplus wireless card, specifically kernel dumps every couple of hours. I have an old (really old) tower sitting in my room which I would like to turn into a wireless bridge so that I could connect the windows box to the internet without dealing with the blue screens. I plan on using Knoppix as I have it available already, but if it would be easier with another distro I can always download it. If this doesn't work I'm going to have to buy an old WRT54G offline and convert that with DD-WRT...

Ubuntu Networking :: Using Tomato Router As Wireless Bridge

Feb 5, 2010

Using Ubuntu Server 9.10 x64 and a tomato router to act as a wireless bridge to connect to another router. The reason I ask is because I do have the router set on WDS mode on the tomato firmware. I think I have it configured to the best of my ability, but when the interface is up, the signal doesn't get pushed out (no received packets) and it gives something at the bottom of an ifconfig eth0 "Interrupt:28".

Ubuntu Networking :: Share Wireless And Bridge To Ethernet

Feb 26, 2010

I'm trying to share my ethernet via my wireless card. It doesn't work. Here is some info:

lspci

05:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02)

lsmod

I've tried everything listed in these forums but every time I run
sudo iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.

I tried the STA drivers and get the same thing except the kernel module loaded is wl instead of b43. Is it even possible to set this card to master mode? I can't find jack on the net.

Ubuntu Networking :: Enable Wireless Bridge - No Corresponding Option

Mar 24, 2010

I want to create the following network:
I have a Belkin 54g ADSL Router/Modem connected to ADSL
I connect my laptop (Ubuntu 8.04) wirelessly to this router
I have a Netgear DGN2000 Router/Modem with NO connection to ADSL
I connect my desktop to the Netgear using a wired connection
I want to bridge the two routers and use the internet on the desktop

The Belkin 54g Router setup has options for Wireless Bridge.. I have selected "Enable Wireless Bridging"; as far as I can tell there is no corresponding option in the Netgear DGN2000's settings to act as a wireless bridge. I have changed the ESSID, Security, and Channel all to the same settings and when I turn on the Netgear router the signal strength of the network dramatically increases. I am unsure whether this is the "Bridge" connected... or if the Netgear's signal is just drowning out the Belkin's signal. In any case I cannot use the internet when connected to the network with the Netgear turned on. What do I do?

Or is there some way I can share internet like this:
wireless wired
ADSL--->Belkin54g----------->Laptop-------------->Desktop

Ubuntu Networking :: Wireless To Wired Network Bridge

May 3, 2010

I am running ubuntu 9.10 on a dell xps m1530 laptop dual booting with windows 7. I am trying to achieve the following setup.

Wireless router <=========> Laptop <-----> Switch <-----> PS3

---- wired
==== wireless

Both laptop and ps3 have static ip addresses

The reason for this is I can connect to the internet on my ps3 through my laptop, and I can stream from my laptop to ps3 through wired connection. This works fine in windows 7 all I had to do was right click bridge connections. As I dual boot I don't want to have to make any changes to the settings on the ps3.

My interfaces are:
eth0 - wired
wlan0 - wireless

I installed bridge-utils and created a bridge and added both eth0 and wlan0 to it. However I could not get it to work. I have also tried internet sharing through network manager and firestarter.

My setup is above, I hope it comes out OK on this forum, and someone can understand what its supposed to be! My problem is I am not sure how to get [PC] to be able to see [Internet]. From [Laptop] I can get both networks to work, and have tried using brctl to bridge them, but as soon as I do "ifconfig br0 up" neither network... works anymore (cant ping either router).

Fedora Networking :: How To Bridge Wired And Wireless Connections

May 29, 2009

My current network setup at home is all wired, and that's worked for me so far. Now I want to set up a wireless connection on my Linux box that I can connect to with both my laptop and my Nintendo DS. I'd like to be able to host a wireless network from the Linux box, connect to it with some other wireless device, and have the wireless device communicate with the router, the internet, and other computers on the wired network. I have the wired network set up (statically configured) as eth0. Other network adapters present on the system are eth1 (not in use) and wlan0, wlan1, and wlan2 (identical cards, remnants from the last time I experimented with wireless).

So I guess my question comes in two parts:
1) How do I set up wlan0 such that it can host? Is Ad-hoc mode okay for this, or do I need to set it up in Master mode?
2) How do I forward connections between the wireless net and the router?
Note that I will be using WEP, as it is all that the NDS supports. I'd like to set up MAC filtering as well, but not until after I get something that works.

Ubuntu :: Use Old Laptop As Wireless Bridge?

Jun 11, 2010

I have an old laptop, which doesn't work, as the hard drive died, and can't be detected. I only recently considered trying ubuntu, so I put in the live CD, and it started, although it was very slow. Wired Internet worked, but of course there was nowhere to install drivers for wifi.

When I want to connect my Xbox 360 to the internet, the only solution I have currently is to use my working laptop. In windows, I rightclick on both the wifi and ethernet, and bridge them.

Now, this isn't a great solution, because it means nobody else can use the laptop at the same time, so my family basically say I can only use it when nobody else wants to. Which is never. So it occurred to me that since I'd only need to use the ethernet port and the wifi card, I could set it up as a permanent solution to my gaming needs. Obviously a Live CD wouldn't work; it would have to be a live USB. I can easily get that sorted, but is this viable? I don't know if bridging the connections is viable in Ubuntu, but I'm sure there must be some way, considering how versatile it is.

In case it helps, my old laptop is an Inspiron 1525, with Broadcom wifi card. My new laptop (although I doubt this has any relevance) is an Inspiron 1545.

PS - Is 'wireless bridge' the correct term? It sounded about right when I typed the title.

Ubuntu :: Wireless Bridge Between Laptop And Desktop Computer

Apr 22, 2010

So what I'm doing right now is I have my laptop connected through my wireless internet (Ubuntu 9.10), and I have a Xubuntu 9.10 Desktop right next to it with an ethernet cable going from my laptop to the desktop. Right now it says it's connected, but I can't connect to the internet. What I've done is I've gone on both computers and edited the settings for eth0 to share with computers, and I've even gone into the wireless settings on my laptop and edited it so Ivpc 4 setting's method was set to share with computers. I downloaded the bridge utility on my laptop but I don't know what to do with it exactly.

So here's the setup I've got going.
Wireless Router ----->Laptop -------->ehternet cable ---------> desktop computer.

Debian :: Bridge Setup - Cannot Connect To Any Wireless Networks

Apr 12, 2011

I am a (somewhat) newbie to Linux (but have an extensive Windows background), and I have just installed Debian Squeeze in an old EeePc 701 4G using the netinst version only with the following packages:

eeepc-acpi-scripts
x-window-manager
gnome-session
gdm
gnome-themes
gnome-themes-extra
plymouth
bridge-utils

Now I would like to install Debian in my main laptop, but I think it won't be able to connect to any wireless networks during setup and before installing firmware-brcm80211 and wireless-tools (its wireless card is a Broadcom 43224AG). That being, and to avoid connecting the computer directly to the router (it is not easy), I would like to bridge the EeePc's wireless connection to my laptop using a cable. I tried using the instructions found at the Debian Wiki, but I couldn't set it up properly.

Ubuntu Networking :: Getting A Bridge Constructed?

Dec 13, 2010

My first, followed a couple of Ubuntu how tos and used LinuxFoundation bridge doc. I still have managed to mess it up! Here's the simple test network, First -- ALL hardware is fine, I have verified everything, to the last cable. In fact this is being written from the test network without the bridge running.

OK, I have a firewall that has dhcp server on board, I have a client workstation with dhcp enabled network card(eth1) (the one I current typing from). There are 2 switches between the firewall and the workstation (eliminate xover issues when testing) That's it. All is well. Now I want to place a computer in line between the firewall and the workstation. It is a 10.04 server install, no gui, minimal install. It has 3 network cards, One of these ports was used to set up the server. It is set up dhcp and it works just fine, I spent all kinds of time ssh'ing into the box, so the dhcp client is good to go.

I disconnected the cable to that interface and ran a cable from the firewall's switch to one free port(eth0) and a cable from the workstation switch to the other free port(eth2). From the console I do ifconfig -a and there are all 3 eth's, 0,1, and 2 I then open /etc/network/interfaces and to lo and eth1 I add this:

Ubuntu Networking :: Bridge Two Subnets With A Server?

Imagine I have a network on floor 1 with an independent cable connection to my Ubuntu server -> switch -> assorted devices, on the subnet 192.168.0.x Now imagine friends upstairs have another independent network with cable -> router -> assorted devices, on subnet 192.168.1.x.

How can I set up my server to provide access for the 1.x subnet to the 0.x and vice versa. Ideally the devices all access internet from their appropriate subnet. I've read something about bridging, is this what I need?

Ubuntu Networking :: Connecting To Internet Through Network Bridge

Nov 13, 2010

I setup a network bridge on pc A, with windows 7 installed on it, using windows default bridging tool. I connected computer B to computer A and Im trying to connect to the internet through the network bridge on computer A. Computer B (client) has two OS's installed, win XP and linux(tried with different distributions, didnt work). On windows XP everything is working, when i try to ping the router (after computer A) it also responds. On linux system nothing is working, and im not quite sure why.

I set up linux to receive IP adress from DHCP, which is router in this case (behind computer A), same way windows XP was configured. I decided to ask here, because I couldn't find anything on the net. My guess is windows-made bridge supports only windows-OS's but that would be kind of strange (its just a software bridge).

Ubuntu Networking :: OpenVPN Bridge Mode Firewall?

Nov 7, 2010

I have OpenVPN running on my Ubuntu Server just fine. I can connect over the Internet and access all my resources on the LAN via bridged mode perfectly. My server only has one LAN card and sits behind my router, which means it has a private IP address of 10.1.1.2....Which brings me to my question. I want to open up access to my friends via OpenVPN, but I don't want them to be able to access other machines on my LAN (e.g. 10.1.1.20). However, I do want them to be able to talk to each other and pass broadcasts (old LAN games), as well as my laptop (let's say 10.1.1.7).I've tried using iptables to block traffic to the LAN (such as .20), to no avail. I've been reading up and it seems as though iptables won't even filter the traffic, as it's passed at a lower layer. Is this true? If so, what do you recommend I do in order to prevent my buddies from accessing the rest of my LAN while siumultaneously allowing broadcasts pass for some very old Windows LAN games (we're talking Windows 9.
