Default My first Gateway and LAN having issues

Hello BSD people,

For the past few week, this is my first attempt at actually hooking computers together in any kind of fashion. I read a lots of examples and no matter what I tried my set-up would not working completely and this is the best I came up with so far ...

From my internel Windows LAN machine I can ping the Gateway but I CANNOT ping any website by name or number (ping yahoo.com or 67.195.145.137). I also cannot surf the INTERNET using any web-browser, IE, Opera or Firefox.

On the GATEWAY machine I can ping to the out-side by name or number but I CANNOT ping my own internal Windows LAN machine.

At one point I could not even ping a website by name because of my packet filter rules (I know nothing, just using something I found) so I disconnected pf by way of rc.conf to see how far I could get. As you see I been stopped again and I have ran out of ideas for trial and error by adding or disconnecting stuff. It's like the only thing available to do is pull-the-plug and call it quits

Kind of long but here's all the info I could find. If there is more related files I would really like to know where FreeBSD put them so I can add it to this list.

Could someone please tell me what am I'm doing wrong or what did I forget to do? Networking is not as hard as I once thought but I am shock after all of these days of reading and what-nots, I'm stuck.

Thanks in advance

When I click IE-7 on the LAN machine to go to www.google it fail.
So I set the Sygate firewall on the Windows machine to Allow-All
and it still fail. This is what I get from Sygate. Lucky I
have it insstalled or I would see no info.
