Setting up a dhcp server on a bridge

Mithrilhall · 02-19-2008, 09:22 AM

I'm trying to setup a dhcp sever on a bridge.

Interfaces are:

eth0 - connected to the internet
eth1 - internal connection to switch branching to other PCs
br0 - bridging eth0 and eth1 together

Internet <--> Public IP [Router] 172.16.136.1 <--> Linux Bridge <--> Switch

I need a static ip address on br0 (10.150.125.2) and want dhcp requests to only be accepted on the eth1 side. How would I go about doing this?

I currently have it working but dhcp requests are accepted on eth0 or eth1.

well what's happening is the very point of a bridge... i'd suggest looking at ebtables to filter them out.

Thanks.

I've found an interesting link that looks to do exactly what I need. http://forum.openwrt.org/viewtopic.php?pid=31952
