  Client machine being anyone from the outside world. And I have looked over
some of the documentation. Basically there is no current firewall policies. Just
want anything coming in on xxx.xxx.xxx.xxx:443 (Internet Machine) to be routed
to 10.10.1.110:443 (Internal Lan Machine). Looks like I need to mangle the
packet header so that the Lan machine thinks that the Internet machine is
sending the packet and then have the Internet machine redirect the packet to the
client. Client again being someone on the Internet. Not sure if this can be done
or not. Correct me if I am wrong.
