Thanks Grant, I am very new to combining NATing and Brigdge. Please can you possibly give an example on how to add the virtual interface. Current /etc/networking/interfaces looks like this: --------------------------------------- auto lo iface lo inet loopback auto br0 iface br0 inet static address xxx.xxx.xxx.xxx netmask 255.255.255.128 network xxx.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx gateway xxx.xxx.xxx.xxx pre-up /sbin/ip link set eth0 up pre-up /sbin/ip link set eth1 up pre-up /usr/sbin/brctl addbr br0 pre-up /usr/sbin/brctl addif br0 eth0 pre-up /usr/sbin/brctl addif br0 eth1 ----------------------------------------- Kind Regards William Bohannan -----Original Message----- From: lartc-bounces@xxxxxxxxxxxxxxx [mailto:lartc-bounces@xxxxxxxxxxxxxxx] On Behalf Of Grant Taylor Sent: Monday, May 28, 2007 6:39 PM To: Mail List - Linux Advanced Routing and Traffic Control Subject: Re: 2 NICs Bridge + Router On 5/28/2007 8:12 AM, William Bohannan wrote: > Hi wondering if anyone can help.

Why not add virtual aliased interfaces to the br0 interface? Do your NATing there.
