For those of us who have SBS Premium internally and manage client SBS servers, the following is an important manually created rule for allowing the 4125 RDP proxy port out:
If one does not create this rule, there is no RDP connectivity allowed out of the internal network to any external SBS server's RWW based RDP session.
For clients, this is no big deal, but for those of us who manage SBS networks, it means not being able to connect to remote SBS and XP Pro/Vista Business desktops via RWW proxied RDP.
