VPN client. RDP problems (Terminal Server) after migrating from PIX to ASA
I have migrated from PIX515E with VPN client configured and working fine to a pair of ASA 5520 with active-standby scheme. All is working fine but I have a problem with RDP and file sharing.
When I connect to the VPN with the client I can ping the server, and I can access to shared folders, but almost everytime I get disconnected from the server with "Encryption Error" at Remote Desktop client. VPN client keeps connected and I can ping the server.
Whe I am connected to the VPN I am able to begin copying files but after some seconds or minutes the file transmision gets disconnected. VPN clients keeps connected and I can ping the server.
I have tried to set MTU to 1300 at client and I have configured "sysopt connection tcpmss 1300" at ASA with no luck.
