Netopia 4652 SDSL Router:

The Netopia 4652 SDSL Router provides excellent network performance in a compact case. Security features are quite good, with "packet filtering" and NAT onboard. Panix can configure these features to suit your needs. Using NAT, you can run your entire network from a single real IP address.

This router can connect an unlimited number of computers to your DSL line.

See Netopia's product specs for more details on this item.

Please call us for current pricing; but as of August 2009, the current price for the 4652 is $289.00 before any taxes or fees. This router will have a manufacturer's warranty

If you change your hardware's configuration without first contacting Panix, and then require Panix's help to reconfigure it, your account will be subject to a $50 charge.

About NAT:

NAT is an acronym for "Network Address Translation". This software technology allows you to use lots of IP addresses on your network. You can even use addresses that are not "routable"- that is to say, addresses that the rest of the Internet can not know how to reach. It is common practice, when using NAT, to use addresses of the form 10.x.y.z (the "10" net). There are 16 million such addresses, so you're not likely to find yourself running out of room.

If you're using unroutable IP addresses, this of course makes your network quite secure, but then how can people reach you (or more specifically, your web and mail servers, and whatever else you want them to be able to reach)?

NAT solves this problem. It takes a routable IP address and modifies all the traffic coming to and from that IP so that outsiders see all your traffic as coming from and returning to that single routable address.

NAT then keeps track of all these modifications; so that all traffic headed for users of your LAN is properly segregated and directed.

Using port forwarding, NAT can also transparently forward a mail or web request to your mail or web server on your LAN.

As an incidental benefit, NAT protects you from many security exposures, since most machines on the inside of your NAT network won't be attackable from the outside at all.
