Bridging with only external IP

Khas

Hello,

This may be the wrong place to ask this question, but I have been all over the internet trying to find something to help, and I can't.

I have a server, which is a VPS running various services, one of which is OVPN. Routing mode works perfectly, but I would like to have the server issue IP addresses so I can do hostname.domain.com lookups. This obviously requires bridging mode.

I have been following this guide: http://maverick.homelinux.net/blog/?p=196. I only have one interface, eth0, which holds the public IP address for the server. However the minute I start the bridge, I lose all connectivity with the server and have to reboot it externally (thank goodness for VPS admin interfaces!)

I think this has to do with the fact that I'm bridging tap0 with eth0, so everything is just getting funnelled both ways - anything coming in to eth0 goes straight through to tap0 - of course there's nothing there to respond.

How do I resolve this? Do I need to somehow create a virtual interface that tap0 bridges to, that hosts the dhcp for both the bridge and the VPN clients? If so, are there any quides on how to set that up?

It's because when the bridge is created, the bridge does not receive any ip settings. Please in the bridge creation script add lines to set the bridge IP you have for the VPS. If you create bridge manually and remotely - you are out of luck.
