Hi, You could also do this with just one squid instance listening on just one IP address. Let's say that your domain is www.yourdomain.com. On your firewall you route the traffic coming to the public IP that corresponds to your domin to the IP of your squid box (which is listening on port 80). By using a redirector you can separate the three servers; www.yourdomain.com/site1 would be the 172.16.0.2:80 and we call it server1 www.yourdomain.com/site2 would be the 172.16.0.3:80 and we call it server2 www.yourdomain.com/site3 would be the 172.16.0.4:80 and we call it server3 So in your redirector you configure something like (this is the format SquidGuard uses): s@http://www.yourdomain.com/site1@http://server1:80@i s@http://www.yourdomain.com/site2@http://server2:80@i s@http://www.yourdomain.com/site3@http://server3:80@i As you can see, the www.yourdomain.com/site# transforms to server#. You have to have corresponding entries in your /etc/host for your servers. If you need more help setting up something like this, don't hesitate to ask.
