[LARTC] 2 NICs Bridge + Router

[William Bohannan]

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

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