Nortel VPN Router Troubleshooting
Action: Verify that the user name you entered is correct and retype the password
before trying the connection again.
No proposal chosen
Cause: The VPN Router you are connecting to is not configured to handle the
authentication method configured under the current connection profile.
Action: Verify that you are using the correct IPsec parameters, such as a choice of
ESP-3DES with SHA1. Make sure it matches what the client (for example, an
International client) can do.
Other IPsec errors
Cause: Typically other error messages indicate an error in configuration on the
VPN Router that the network administrator must correct.
Action: Contact your Network Administrator with the specific error message.
Extranet connection lost
If the PPTP or IPsec VPN Client connection was initially established and then
fails, one of two error messages appear: The physical connection has been lost or
The secure extranet connection has been lost.
The physical connection has been lost
Cause: The PPP connection to your ISP was disconnected.
Action: Re-establish the PPP dial-up connection to your ISP before you
re-establish the extranet connection to the remote network.
The secure extranet connection has been lost
Cause: For IPsec only, the VPN Router that you are connected to has either
logged your connection off or is no longer responding.
