You can have more than one external ip address (extra's go in
ETH0_EXTRA-ADDRESS="" variable). You port forward by ip address, so
if you specify the proper addresses going in and out, this is entirely
possible.

You can easily add extra internal networks/subnets as well by configuring
the interfaces with the proper information and adding the extra internal
interfaces to the variables:
INTERN_IF="eth1"              
INTERN_NET=192.168.1.0/24      
INTERN_IP=192.168.1.254

IIRC, multi-homing w/Dachstein wasn't much fun, though possible as well.

I hope this helps!
