Keep in mind that PPP mode can work in both a NAT setup, or a routing setup. In the NAT setup, all of your public IP's get assigned to the WAN interface on the DSL modem. In route mode, only one of your IP's get's assigned to the WAN interface, and it routes the packets for your other addresses to the inside interface. If your ISP gives you multiple ip's, you can make it route instead of doing NAT, so your machines actually get public IP's. Of course, if you do this, you'd better make sure the machines are locked down tight. Or you can assign the public ip's to a firewall, obviously. :) Jay
