I believe the current installation tools will set things up at install time, but I am not aware of any tools for reconfiguring your network. I have a similar setup to yours and edited /etc/network/interfaces to add the address, netmask and broadcast address for my second ethernet card. After doing this running (as root) '/etc/init.d/networking restart' should initialize the interfaces. For masquerading, you need to make sure your kernel has firewall, ip firewall and ip masquerade support included. I compiled these into the kernel instead of using modules, but that should work as well. If you install the ipchains package, it should set up a reasonable set of firewall rules for you. Bob
