If the VPN server accepts your name and password, the session setup completes. As a result, the L2TP layer doesn't see a response to its connection request. There will be a long delay, typically 60 seconds, and then you may receive an error message that says there was no response from the server or there was no response from the modem or communication device.
If you receive this error message before you receive the prompt for your name and password, IPSec didn't establish its session. If that occurs, examine your certificate or preshared key configuration, or send the isakmp log to your network administrator.
Many small networks use a router with NAT functionality to share a single Internet address among all the computers on the network. Home networks frequently use a NAT. For more information, see the "NAT Traversal" section. If the connection fails after you receive the prompt for your name and password, the IPSec session has been established and there's probably something wrong with your name and password.
