I appologize for the inconvenience. I will try to be clearer.

I tried accesing the FreeBSD box from the 2 other computers
I have. Also I tried telneting from the FreeBSD box to itself.

Unfortunately, yes. I tried pinging outside computers by
IP address but I can&#263;t anymore.

Yes, before I started messing with the firewall I had squid
set up, I set up FreeBSD as a gateway and also as a DNS
server. I could acces the WWW, ftp, telnet and all the
other services at will, inside and outside my home LAN.

I was thinking maybe I misplaces the setup keyword in my
firewall rule file. Did u happen to see it, I posted it in my
last mail. I don&#269;t understand how ftp works and my
proxy serevr doesn't if I used the very same and exact
syntax to define the rules.
