Hi Eveybody,
Recently one of our client has provided the VPN to us for conencting. Its a Cisco vpn client. The vpn connects fine, but after connecting, the remote desktop to the servers does not works.
to brief about the setup, the users are lying in a vlan, created on a Cisco ASA 5520. We have a access-list on that firewall allowiing full ip traffic to the client's vpn gateway. After that there is another perimeter firewall allowing access to Internet. On that we have done a static one-to-nat for the user machine trying to connect to that vpn.
When the user is int the vlan behind the Cisco ASA 5520, the vpn connects but remote desktop does not works. But once we move the machine out of the vlan to the normal network out of the firewall Cisco ASA 5520, the vpn connects and remote desktop as well works fine.
Below are the logs i have captured which are relevant to the problem. Please suggest how can this issue be solved. Sicne we have to have those machines in the vlan.
