I am needing some help setting up a VPN connection between two branchs of a business. Both have broadband connections and a small LAN with max 10 pcs on internal network. Both branchs have static IP public addresses, but I cant seem to connect. I have configured the router to forward VPN incoming TCP1723 to local static ip of VPN server XP pro and firewalls on the server to allow incoming VPN and remote desktop. Is there any other ports I need to open on the router.
