My VPN connection has been working but now after several hours I cannot connect.
My LAN is working. (Windows Server 2003)
Cisco Systems VPN Client
The error message:
Initiating TCP to 184.108.40.206, port 10000...
Contacting the gateway at 220.127.116.11...
Failed to establish a secure connection to the security gateway.
What could be the problem?
on the tunnel properties -> transport mode, click ipsec over UDP and try connecting.. I think right now you are connecting through TCP 10000.
