I'm currently working on a replaceThePIXwithLinux project. What I'm hoping to do is: This will be the *only* way out of the LAN. This is to be enforced with pieces of wire. If they can get into the wiFi next door, I don't have a solution for that yet. This box will transparently proxy HTTP by intercepting port 80 (and 443??) and forwarding it to 3128. Squid will be running on the gateway / filter / firewall. Aside from a few ports (SMTP, POP3, IMAP, DNS, etc. on the DMZ), the LAN won't be able to go anywhere. Except for me, of course; I can go anywhere... Don't know if this is going to work, but if it does, rules similar to these may solve your problem. With no proxy whinage. -- Glenn English g...@slsware.com
