Troubleshooting

Mismatches of Preshared Keys

It is easy to mistype a preshared key at one end or the other of a LAN-to-LAN connection. If you are

sure your IP addresses are correct, but are unsuccessful in bringing up a tunnel, make sure the preshared

keys on either side of the connection match exactly. Entries are case-sensitive.

Mismatches of Parameters for IPSec SAs

If you cannot PING from the private interface of the local gateway to the private interface of the

destination or remote gateway, there is likely a problem with the security associations. Check that the

values for all parameters for the SA on the local network match those values on the remote network

exactly.

Configuring Event Classes

You can configure specific event classes and severities for special handling. For troubleshooting a

LAN-to-LAN IPSec connection, add the following event classes, all severities (1-13), to have the

Manager send these Events to the log or to the console.

In the Concentrator Manager drop-down table of contents, click Configuration > System > Events >

Classes. The screen of that names displays.
