HTTPS (RWW, OWA, remote desktop or Terminal Server sessions) Port 987 TCP . External secure Companyweb access Port 1723 TCP . PPTP (VPN) If port 80 is not open, then you must specify https:// for RWW connections; otherwise if port 80 is open you can use http:// and the session will be redirected automatically to port 443. If your router is configured to use UPnP, the Internet Address Management Wizard (IAMW) will open port 80. |
