Problems with nat installation

Hi there,

I need some help configuring nat for some simple gateway. I have edited the
routing table according to my situation and the squid qroxy is doing fine.
Only direct connections don't work due to nat is not configured yet. I dont
want to mess with a complex firewall installation. I only want a simple
gateway. Maybe someone already has some similar configuration running and
has some clues for me.
