okay.. I was thinking that your ISP box *could* plug directly into port 1 and have NIC1 on port 2.

 

You then have your IP-facing IP address (11.22.33.44 or so) on eth0 and your private IP (192.168.1.2) on eth0:1.

 

Any machines plugged into port 3 & 4 on your switch will need to obtain a 192.168.1 IP and be told that 192.168.1.2 (your machine) is the proxy.

 

However, this is a somewhat dangerous setup because it will have *all* machines potentially internet-facing, and one wrong IP change could expose something unprotected.

 

Is there a firewall on the ISP box ?
