Can't access port 6666 through VPN

Archived from groups: comp.dcom.vpn (More info?)

I have a VPN setup on my Windows Server 2000 machine. The only port open is
1723 from which I access with the VPN and then I can initiate Terminal
Services without having to forward any other ports... pretty standard.

Here's the twist:
I'm trying to access a program on the server from home via the VPN that is
setup to run on port 6666. Everything works great on the LAN at work, but
my home PC cannot seem to access port 6666 through the VPN. The only way I
was able to get it to work was to directly forward port 6666 on my linksys
router to the server's IP. However, I don't want to have to open a 2nd port
to the outside. Why can't I access this port via the VPN through 1723? It
seems like it should work just like Terminal Services.
