I listened to your advise and here are the following changes that I
made:

1) I changed the SSL server running on the firewall to run on port 443
instead of 445 to avoid any confilct.
2) I attempted to open ports 135-139 udp and tcp and there was no
effect.
3) To see if I needed RPC or not, I enabled IP Filtering on the WinXP
machine and only allow port 445 for tcp and udp. I'm able to connect to
the test share I have setup with no problem from within the firewalled
network, but still cannot connect externally.

Any more ideas at this point? It would appear that all I have to do is
forward port 445 for it to work. So, I instead tried to setup the WinXP
machine to accept incoming PPTP connections so that I can connect that
way. But when I try to connect to the computer via PPTP, I get one of
the following errors:
1) TCP/IP reported error 733: Your computer and the remote computer
could not agree on PPP control protocols.
2) Error 6: The handle is invalid.
3) Error 668: The connection was terminated.

Now what the heck is the problem?
