We have an IPsec Site to Site VPN connection between Cisco 2911 router, (Home Office) and Cisco 861 router, (Remote site).
1. Users behind 861 router ARE able to access resources behind 2911. Site-to-site working great.
2. Users behind 861 ARE able to establish RDP connection to Terminal Server IF they use Public/Wan IP address, as in: 172.164.x.x:3389.
3. However, users behind 861 ARE NOT able to establish RDP connection to Terminal Server IF they use Terminal Server LAN IP address, as in: 10.11.X.X:3389. Receiving “Remote Desktop Can’t connect to the remote computer” …. Error.
4. Remote users utilizing established Cisco VPN Client connection, NOT behind 2911 or 861, ARE able to RDP to Terminal Server IF they use Server LAN IP address, as in 10.11.X.X:3389
Appears to be issue with RDP while utilizing Site-to-Site. Any thoughts or suggestions would be greatly appreciated.
