definately try port forwarding first though, read ur router's
documentation and try to figure out if u can solve ur dilema with port
forwarding alone
unfortunately, if u DMZ ur computer then u loose the security that the
router gives u
port forwarding allows u to punch holes in ur firewall but still maintain
the security that the router offers

port forwarding is safer, but if u have no idea what ports to forward or u
want the ISP's IP to actually point to a comp in ur local network then u
must DMZ that computer

Obviously you don't understand NAT. Just consider the IP address your
computer is reporting as the real IP address of the computer. It is
unreachable from the Internet under normal circumstances, so your router
is using NAT in order to foreward packets from your system (i.e. request
objects) and to figure out where to send responses. The "alias" looking
IP address you see coming from the laptop is not put there by your ISP, it
is put there by your router as part of NAT.
If you want to reach your laptop from outside of your home network, you
are going to have to resort to port forwarding -> refer to the
documentation for your router for how to set that up via the router's
admin interface. It is also dependant on your ISP allowing incoming
connection requests, many do not.
Oops. I just noticed this is the tomcat users list, so the advice I'll
give you ends here as it is inappropriate for this list. Use Google to
look up NAT protocol, or join an appropriate list in order to get more
information about NAT devices. Also read the documentation for your
router.
Rod.
