Yes, most of the WAPs I've seen allow this. Another option I use is to
set the machine to establish a tunnel with a machine that does have a
public IP address. Any host with SSH service (even the cheapo mail-
only accounts) should suffice. Then just run SSH to that public machine,
contacting your firewalled machine on the appropriate port. (I usually
do this for mobile devices.)

For example, if you run "ssh -R 2250:localhost 22 publichost" on your
firewalled host, you can get to it from the outside using something like
"ssh -p 2250 publichost". (You might want to check out Rocks or Reliable
SSH to keep the tunnel alive.)
