Hi wondering if anyone can help. I have two NICs on a debian sarge based system and current running as a bridge (br0) which consists of eth0 and eth1. Is it possible to add a virtual interface to the eth1 so I can also do NAT on the box as well? I have tried many times and keep coming up with errors. Kind Regards William Bohannan

Hello, I how an embedded processor that needs to act as a bridge between a wireless and wired network. I have managed to bring up the bridge fine. I can also bring up the bridge with a static ip address. However I can not figure out how to bring up the bridge with a dynamic ip address. Is it possible to for a bridge to get a dynamically assigned ip address? Oliver

Hi, I'm using linux 2.6.21.5 and our kernel is freeze. The problem is, if I create a Software bridge using $brctl command. and add two interfaces say, eth0.0 and eth0.1 using $brctl addbr br-lan $brctl addif br-lan eth0.0 $brctl addif br-lan eth0.1 and when i send traffic from a host connected to one port to host connected at other end, soon all the memory is dried up and and kernel crashes, then oom-killer gets invoked which kills all the processes finally system reboots. I googled for solution o...

...r a second problem when writing the link monitoring code. When you add a vlan interface like eth0.10 then it's not possible to obtain link state information from this interface. The fix I wrote is that brctl now allows you to specify the interface that contains the link state. Example : brctl addif NUM1 eth0.10 eth0 The old syntax: "brctl addif NUM1 eth0.10" still works but the link will always appear to be up. "brctl addif NUM1 eth0" works with link detection since this is a valid 'link state providing' device. If anyone is wants to know how to use the linux br...

...| | | ppp0 ppp1 eth3 ppp3 I've read that anything can be bridge as long as MTU is the same. Since PPPoE has ethernet headers, i'm assuming that each of the devices ppp0, ppp1, ppp3 have those as well. Is bridging them together as simple as: brctl addbr br0 brctl addif ppp0 brctl addif ppp1 brctl addif eth3 brctl addif ppp3 ?

I've got a 2.6.8 kernel with bridging enabled as a module, two nics (LNE100TX and RTL8139) and i've run the following commands with no errors modprobe -v bridge brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 both interfaces have 0.0.0.0 as their addresses and brctl showmacs br0 shows the macs for both internal cards. However, bridging doesn't seem to be working at all. What am I missing or what else can I try to debug what might be wrong? thanks

Hello all, I'm trying to bridge the wlan0 and eth0 on an embedded system. I used the following commands to setup the bridge: ifconfig eth0 0.0.0.0 promiscuous ifconfig wlan0 0.0.0.0 promiscuous brctl addbr br0 brctl addif br0 eth0 brctl addif br0 wlan0 brctl sethello br0 1 brctl setmaxage br0 4 brctl setfd br0 4 ifconfig br0 up The eth0 is connected to a local network, and wlan0 is set to Ad-hoc mode with proper SSID. After the bridge is stablized, I use dhclient to assign an IP for br0. Then I use a laptop to conn...

Device to my KVM host running CentOS 6, and for the life of me I can't get this going. >From all my research if I want to add a device I should just do 'brctl addif br1 vnet14' if I want to add a vnet14 to bridge br1. When I do this, I get: # brctl addif br0 vnet14 interface vnet14 does not exist! If I run a 'brctl show' I get the following: # brctl show bridge name bridge id STP enabled interfaces br0...
