Configure a DMZ Host.

You can have a single IP *completely* exposed to the internet. This limitation of only one machine *wide-open* is because you only have *one* IP address on the WAN/ISP side of your router...

Or, you can simply port-filter and direct specific ports (individual or one or more ranges) to a given IP address inside your LAN.

Only *some* DSL Modems can be reprogrammed/flashed to offer NAT, and the software upgrade typically runs $40-60, "for a few dollars more" you could have a dedicated piece of hardware that would work with anything you migrate to (Cable/DSL/LAN direct connection).

HTH,

Ken

I've looked at those things.  There is a flash upgrade for the DSL modem
itself that makes it do NAT.  There is one big thing I've been concerned
about.  With a linux NAT box, I can run things that are allergic to NATs
on the NAT box (gnutella and other P2P networking systems (games) seem to
be a prime example of things that seem to be allergic to NATs).  If I have
a dedicated NAT appliance, how would I work out things that don't get
along with the NAT?

Does anyone else have experience with this?
