TMG on 2008R2 - not showing PPP adapter RAS Server affecting VPN

Hi All,

I have interesting issues with an ISA 2006 SP1 to TMG2010 SP2 RU5 migration installed on 2008R2 Standard Edition. It is part of a migration /upgrade project. The TMG server is prepped and installed with the TMG software and imported the ISA configuration followed by repairing the Cert and Networking issues as the new server has a new FQDN and new set of DMZ and Production IP addresses. Initial testing has gone well and can confirm that all the web listeners are working and routing to the correct destinations. I have stumbled across an issue that I am trying to resolve with VPN. VPN is configured on the TMG and understand the RRAS is controlled by the TMG software. I have a Static IPV4 Address pool assigned and from the looks of things it all looks okay except that the Internal interface on the RRAS setting do not get an IP address assigned and remains IP Address = "Not Available" , Operational Status = "Non-Operational" , Administrative Status = "Unknown". I have also noticed that when I do a IPCONFIG /All , I don't see an "PPP adapter RAS Server" at all. I have removed the RRAS Role , with NPS and ran through the TMG Prep that reinstalls the Server Roles and Features , followed by a repair of the TMG software , however it does not cure the problem. I have been doing a lot of research and forums suggest the checking the ports GRE and the other ports. Note that L2TP and PPTP is enabled as default on ISA and these settings were migrated to the TMG. the Experience from a user using WIN7 with the standard WIN VPN comes back with an error 789 and expected as the current TMG VPN does not look like it is fully operational.

Any steer or guidance on this topic will greatly be appreciated.

Thanks
