ahh ... du skal nok lige kigge lidt nærmere på "netværks konfiguration" ifm RWW (remote web workplace).
dette er taget via google... Der er nogle ting omkring SSL/RDP/RDP gateway osv ifm. firewall
Personligt har jeg aldrigt brugt RWW ... såe det bliver desværre lidt i teorien ..

The Remote Web Workplace is a Web-based application and is accessed through a web browser. To control remote computers, a user is required to install a "Remote Desktop ActiveX control" into his/her web browser once, and only Internet Explorer is supported.
RWW works by proxying Remote Desktop via port 4125/tcp on earlier versions of SBS and via port 987/tcp on current versions of SBS to the usual RDP port (3389/tcp) on the internal client or server machine being reached. As a security measure, port 4125/tcp and/or port 987/tcp is not normally listening for incoming connections. The RDP Gateway service will only accept connections from the IP address of the user who has requested a RDP session via the web GUI. All other connection requests will be ignored producing "Connection refused" errors. The established proxied RDP session continues until the session inactivity timer drops the connection or the user disconnects. The usual RDP port of 3389/tcp is never exposed to the internet for RDP sessions established with RWW.
To support RWW, your firewall will need two rules to redirect incoming tcp traffic for HTTPS (port 443) and for RWW-RDP (port 4125 and/or port 987) to your SBS server.
