Just do a bare debian install and put something like the file below in
your /etc/network/interfaces, it's what I use.

eth0 is outgoing, eth1 is internal network.  Change eth0 to a dhcp
config if that is what you use.

I also use dnsmasq as the dhcp server for the internal network.

IP addresses variable'ized to protect the innocent :-)
