Hi,
I would like to get a nice (and free) firewall for my home LAN, on a XP gateway.

I have used an old PC for this, running Linux with web proxy, web content filter and a firewall.

Now I would like to do the same using XP, but I am a bit lost.

The XP internet connection sharing works fine, but it does not seem to be a great firewall compared to what I used to have with the Linux setup.

Main difference is that I can not block with different rules different PC acces to Internet.
Eg.
LAN PC's should not be able to access Internet on tcp port 80, but the firewall PC should.
-OR-
My PC on the LAN should be able to FTP to the Internet, but my kids PC should not.

It seems the personall firewalls is not designed for gateway use, and of some reason the XP firewall does not support this either.

But im sure this can be done with XP also, I just dont know how
