customization of Guarddog 2.0

[pcghost]

I have finally given up writting an Iptables script from scratch. I downloaded and am installing guarddog 2.0 My only question is once I get the firewall settings in guarddog set, how do I add customized port forwarding?

I need to forward ports 1352 and 25 to an internal IP desperatly...

Any guarddog/iptables guru's (johnT?) have any ideas how I should proceed?

I assume that you are masquerading?

Actually the machine is to be the squid server for a medium sized business network. Squid being a proxy, that's not masquerading is it. That is actually one of my questions. Does one need to add an entry in the firewall script to allow squid to function? If not my only remaining question is how to forward the ports listed above while still using Guarddog for the general firewall configuration.
