Guys I have been trying to set this up for quite a bit now. I installed the guarddog for a firewall and in the help doc it states that guidedog is used to set up forwarding and masq. So I grab the guidedog. The guarddog help says that I need to make a new zone. etc etc I followed the instruction and still no sharing. The physical setup is machine one has two nics(eth0 &wth1. Eth0 is connected to theinternet. Eth1 is connected to my hub. What ever u guys need let me know I will get it for u. I am using debian 2.4.26-1-386.

this was fixed sorry i have no idea what it was i ended up reloading and starting from scratch and all worked
