What im trying to do is RDP to a external address while connected through cisco vpn. at the moment i can RDP to internal addresses (192.168.3....) but not external. i was thinking that the firewall might be blocking the RDP port so i added a rule to allow access out on the port 3389 but this didnt resolve the issue.
External computer ----VPN --> 192.168.99.0/24 ---> server ----> RDP external address
so when external useres connect using vpn they get a .99 address from the server.
