RE: firewalling behind NAT?

[Scott Stone <SStone@example.com>]

yeah that's what I'm doing :)  I have a static IP bound to the internal IP
that the dhcp box gives to my laptop (it assigns same ip every time to the
laptop's MAC addr), and the only thing I allow from the outside to that
static are the directplay ports.. so I can use gamevoice, netmeeting, etc,
on the laptop at home.  seems to work.

Not on a Sumitomo DSL router :-p  It partially works, but not
entirely.  It works better on the latest ones than on the
earlier ones, but is still officially held to be 
unsupported.  Works fine on Cisco.  Probably works fine
if you're running a DSL modem and using a Linux box for
NATting, too (neat little jig to keep this on-topic,
huh?  :-)
