We have a number of Windows XP SP3 boxes, all running the stable RU host. Our users connect from home using the stable viewer, over the stable relay.
Some of our users when at work access a 3rd party network using a checkpoint software solution VPN, specifically check point SSL network extender service (v7.001.0000) and Check Point deployment shell (v8.000.0000). Today the first of these users to connect from home over RU, tried to enable the checkpoint VPN. When that was done, the RU connection was immediately dropped, even though the user still remained connected to the RU relay. The connection icon alternated between online and offline.
