bridging



Hello,

I am running OpenSuse 10.3 with kernel 2.6.22.13-0.3-default on a x86_64. I am trying to get bridging to work, but most of the help pages I find seem to only get me half way there. I have two ethernet ports, eth0 and eth1. Eth1 is my main, static with DNS server running and an address of 192.168.1.11. Eth0 is the one that I wish to bridge. I try the typical

brctl addbr br0
ifconfig eth0 0.0.0.0 promisc
brctl addif br0 eth0

and create a tap0 with tunctl. I should say that I wanted the bridge to be static with an IP of 192.168.1.13. When I restart the network and type in ifconfig -a, it all appears there. But, when I try to do nslookup or ping, both ethernet ports are *broken*, unreachable.

What I wanted was to be able to have my DNS server running and be able to switch my ethernet cable from eth1 to eth0 and vice-versa (since I currently only have one cable). And still keep my services all running and happy.

I basically am trying out qemu with Windows to get my VPN to work working. It cannot be on a NAT. I know that if I can get this working, I will be able to VPN into work and get something done. Any help or advice is appreciated.

1. Does anyone have an idea of why this is not working? How to make it work?
2. Can this be done this way? Or will I have to settle for less?
3. Is the problem OpenSuse 10.3?

Thank you in advance,
Patrick
