Running EQ through a Proxy...Follow

Well i've been trying to get this to work.. here's my setup..

I am on a laptop that is connected to a 5 port switch.. my brothers computer is also connected to the same 5 port switch. The switch is then connected to a 4-port hub in another part of the house, which the internet connection was shared to.. on the main computer with the internet connection, I shared the connection using a proxy program - which worked great for getting the internet to work (such as it is now, otherwise i wouldn't be posting this). BUUT i can't get it to run EQ thru the proxy.. and i researched a bit on the internet, and realized that it can't be done with conventional basic proxy programs. Then i stumbled across WinGate (www.wingate.com) - and it said it could run Everquest.. so i tryed to get it to work.. and bah.. i couldn't seem to figure it out after 3 hours of trying. I tinkered with everything (and the help seemed to mention something about using NAT, so i following instructions to use NAT - but to no avail).

So i'm kinda stuck here.. am I outta luck on getting this working in this current setup? (which is only temporary, but would be nice to have EQ running) Or is there a feasible way to pull it off?

Just wondering.. thanks :)

Alright it looks like im outta luck.. trying to open all ports and what not (which i'm not 100% sure how to do) on the main computer sharing and i'm not sure its all so safe either.. anyways.. no matter - i figured i was dead in the water. thanks :)
