But where do I put the gateway address? What do I do about the etc/firewall file? I seem to remember last time I tried this it didnt accept the gateway address in the ifcfg-br0 file. I know I can probably figure this out but wondered if anyone had done this so that I can just make the change once and hopefully not have to move the server. I should add that the server only has one NIC./quote]

Until about two weeks ago, there was a rather fine manual on how to do this, something mentioning the words "inline" for some configuration. I used the method to get one-nic'ed systems running with it, especially for kvm cases too.

The magic ingredient is one line in /etc/sysconfig/network


The current howtos all miss this point, so I had to manually set a default gw. Luckily, one of the oldest linux commands I had to learn.
ifconfig bro default gw ip.of.your.gateway

In my opinion, having bridged ethernet on one-nic'ed servers is mandatory for most usecases. Same as installing on a lvm, kinda.
