We have a Cisco ASA 5520
We are attmpting to setup RRAS on Windows 2008R2 using L2TP. Server is on the inside of the network at 10.10.10.20 our ASA is 10.10.10.1 its outside interface is 68.0.0.0.3/28.
I set a static NAT rule to allow all traffic pointed at 68.0.0.4 to be directed to 10.10.10.20 and have ACLs allowing the following.
esp, ah, udp/500, udp/4500, udp/1701
Mac Clients have no issues with but windows clients seem to hang and never connect. I know the ASA configuration is somehow to blame, if I atttempt to connect to LAN IP (10.10.10.20) from withn the same network every thing works fine (making sure all the Windows Issues are covered).
Any Ideas would be helpful!
PS. We have 2 other IPSEC tunnels established to teh ASA from our COLO and a Satalite office, not sure if this makes it any harder.
