In the process of migrating to Server 2008 R2 from sbs 2003. Have sbs 2003 still gc and fsmo roles. New 2008 dc is dhcp and dns server. Exchange 2010 running on seperate 2008 r2 server. Have setup rras on 2008 rds server have followed this article http://technet.microsoft.com/en-us/library/cc731352%28WS.10%29.aspx I have forwarded vpn traffic from router/firewall including gre 47, 1723, upd 500 etc When testing it users are getting error 800. Nothing is logged on server. Port query shows ports are open and listening. Can connect to vpn internally in the network. Only thing I can put it down is the router. Any other suggestions? Thanks in advnace.
