Nortel VPN Router Troubleshooting
ISAKMP
[13] Error notification (Authentication failure) received
from xxx (a.b.c.d)
Description: A VPN Client attempted to connect, but the user supplied the wrong
password.
Action: Make sure that the user and the VPN Router have the same password.
Description: A remote branch office rejected your VPN Router’s attempt to
authenticate.
Action: Contact the administrator of the remote system. If the remote system is a
VPN Router, the cause is noted in that system log.
No response from client—logging out
Description: Your VPN Router has lost network connectivity with the remote
side.
Action: Verify the network connectivity between your VPN Router and the
remote side.
Description: A remote branch office using pre-shared key authentication is using
a key that is different from what is configured on the local VPN Router. Because
the two sides are using a different encryption key, your VPN Router cannot
decrypt the encrypted messages from the other side, and therefore drops the
messages.
Action: Make sure that both systems are using the same pre-shared key.
ISAKMP
[13] xxx (a.b.c.d) has exceeded idle timeout—logging
out
Description: The remote system is idle for the amount of time configured in the
Idle Timeout parameter (Profiles
> Groups > Connectivity).
Action: If the Idle Timeout value is too low, increase it. To disable idle timeouts
entirely, set the Idle Timeout value to 00:00:00.
