I tried google but without success. I have a small home network and one computer has to work as a bridge (comp1), it connects to the internet through wlan and is connected with cable to other computer (comp2), I would like to to make that second computer member of a local network with internet access.I was trying this:
I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.
Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?
I'm trying to setup a Centos box to act as a backup server for our intranet between stores. I have two interfaces in it, the first one is currently connected to my local network and is using dhcp to get its ip address and such, the second one is set to a static ip address and is connected to an independent network that just has a DigiBoard Portserver hooked to it and no connection to the regular network. What I am doing is using ssh to portforward the telnet port on this box to the main server so when you telnet into the box from the second interface using the portserver you get connected to the main server.
I plan on using this over DSL lines as a backup when our main dervice goes out to allow the portservers at the remote locations to seemlessly connect to the main server by just moving the network cable from the local net to the backup server. My problem is that when I have the everything working I am able to ping the second interface ip address from the normal network even though the secondary card does not in anyway externally connect to the network, this is a problem.
Eventually I want to duplicate the main server address so that the normal portservers and other terminals on the remote site will not have to be reconfigured to access the backup server. All I want is to be able to tell the managers is to switch a cable while the main connection is down and not have to manage a bunch of config files to get the store back up. Right now if I duplicate the main server ip address and it is accessible through the first interface I'm guessing I'll see all kinds of problems relating to duplicate ip addresses on the network. I've tried some routing and iptable stuff but I'm not real familiar with either so I had no luck. Is there someway to block the internal connection between the two interfaces so the only thing that sees the duplicate ip address is the second interface?
my both linux and windows has 2 network cards each.
basicaly it is vLan cards, each server has 2 network cards. one to main switch and one to local IP.
data will be going like below:
internet ----------------> eth0 --> linux --> eth1 ----------------> Windows.
i have vLans on both servers. And i need cross connection setup. And use linux in bridg mode / cross connection .
actualy i want to use Iptable rules to filter bad packets and forward good packets to windows. i have scripts how to forward packets to windows. but the problem is i dont know how to setup both servers in this topology. and how to make linux as bridge.
All it should be in transparent mode. Not in NAT mode.
I've currently got a Xen box with 3 Virtual machines on it, in a routed setup. I'd like to put them all on a private internal network as well, which I'm assuming I'd do with a dummy network card and a xen bridge, but I can't find any information about setting up the xen Bridging setup on top of the existing network-route instlal.
I have 2 NIC's in a box. One of them is external and doesn't matter for this question I don't think.
The other NIC is 192.168.100.3. It hosts an iSCSI Target and SMB Share on my LAN. It's works great.
I have another PC that has NIC at 192.168.100.101 and it hosts my DHCP (Scope: 192.168.100.5-25) server for my LAN.
I have a hardware firewall at 192.168.100.1 and it serves inet to the LAN on a different external connection.
So...
I currently have a WAP (cheap p.o.s. netgear router in WAP mode that keeps overheating). I want to eliminate the WAP device and add a WiFi NIC to the Top PC above.
So, on the first system I would have:
NIC 1: External IP and External Gateway NIC 2: Static IP 192.168.100.3 Proposed WiFi NIC 3: Static 192.168.100.4
Then I simply put the WiFi in Ad Hoc, will another WiFi in Ad Hoc (for example my laptop) be able to "see" 192.168.100.101 (DHCP) & 192.168.100.1 (Gateway) (via WiFI 192.168.100.4 through the bridge to 192.168.100.3 and on to the LAN)?
Also, can the two NIC's be bridge together even though they are the SAME subnet?
I want to connect my dataone broadband connection in bridge mode in fedora 7. As i am currently using a bridge connection through this modem (smartAX MT882) in win XP, i want a bridge connection in fedora 7 too to access the internet from linux. I have gone through some forums discussing this issue. somewhere i have found the option "adsl - setup" and tried it in my fedora 7. But it is showing the message "adsl- command not found" on this issue. I need a detail step by step procedure for brigde connection using datone in fedora 7.
I'm trying to set up a Linux box with three ethernet interfaces as a bridge where I can do some packet filtering. I don't want this box to have any IP stack, packets that are allowed through the filter should be forwarded without changes just the way a switch would do it. I have build a kernel with ethernet support but no IP stack. It detects my interfaces, and I can bring them up with the ifconfig or ip commands. But when I try to start a bridge with brctl I get this error message:
can't setup bridge control: Address family not supported by protocol
A google search for that error message gave me no results at all. The command I used was "brctl addbr br", which does work on a full installation. Does brctl require IP support in the kernel? That would be a bit odd I think, since brctl doesn't do anything IP related, everything it does is at lower layers?
Does anybody know what the above message means, and what I might have been doing wrong?
I'm sure this is a bridging issue and there is just some option I'm not setting correctly. Also, the reason I'm connecting the Xbox 360 directly to the linux box and not to the router is for traffic monitoring purposes. Note that all connections and functionality work perfectly when the Xbox IS connected through the router.
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:
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.
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.
"I am new to Linux. Could you please guide me how to make ADSL bridge connection. I have tried to make connection using Network manager. But, it some times works and some times doesn't works."
I'm following this guide [URL]. I am trying to use a bridge to vpn from work to home.
/etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback
# The primary network interface auto br0 iface br0 inet dhcp bridge_ports eth0
iface eth0 inet manual up ifconfig $IFACE 0.0.0.0 up up ip link set $IFACE promisc on down ip link set $IFACE promisc off down ifconfig $IFACE down
I am forced to use dhcp because of my router. (although it is a static lease) I think this is where I am hung up. Everything else seems to be working properly though. I have a windows client connecting but is limited to the server serving out openvpn. (192.168.1.21) In other words it is not functioning as a bridged vpn service.

i have 2 network connections eth0 wired connected to internet wlan0 wireless (work fine) i have installed hostapd with madwifi and so on oki when i run hostapd the clients see the hot spot oki clients connect with wpa oki network manager run at demand not automatic (keep it for internet help) now i'm a bit lost what do i need is wlan0 give the client an ip (dhcp demand) create a bridge between wlan0 and eth0 steps to create a permanent bridge between wlan0 and eth0
I have setup hostapd and a bridged setup with br0 bridging eth0 and wlan0. The setup works but unfortunately not on bootup. The reason is that the bridge can't add iface wlan0 because it is down for some reason at this time. When hostapd is running (after the network script) the interface is up and can be added to bridge via
I am new to fedora and I've installed fedora 14, I want to know what are the steps to make my machine act as a transparent (IP-less) bridge? Second, after setting the bridge, I want to make all the packets that passes through the bridge execute a servlet filter (to make some tests and add cookies) is it possible? Is there a simpler way to do those tests on the packets and add cookies?
I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 8.8.8.8 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 8.8.8.8 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !
I want to connect my modem straight to my fedora 13 box, using it as a firewall, and I want to use my wireless card to set up an ad-hoc to give internet to the windows computers in my house. My router has been messing up and I am trying to create a quick fix until I can solve the problem.
My eth0 has internet connectivity but when I use the brctl command to try to create a bridge it doesn't let me add my wireless card, wlan0, and also I lose internet while my eth0 is in a bridge. I am fairly new to Linux.
I have a Gateway laptop running ubuntu 10.04, and just now have a compaq desktop running windows 7, my laptop has wireless internet connection, it's the only way that i can get it in my room. my desktop has only ethernet plugin. My question is, If i plug my laptop up to my desktop using an ethernet cable, can i bridge that connection to get internet from my laptop(using the wireless) to my desktop(using the cable)
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:
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]
