Hi,
I tryed port forwarding but the page connects thru an internal ip address so portforwarding doesn't fix the problem (he uses port 980 fyi), do you want to access the page from an external site or from an ther subnet? From an other subnet you can open the port 980 and set on the workstations the router as primary gateway! An other way is setting up a vpn connection and then try to open the page. Works for me!!!!
Good Luck,
Evdzon
