VPN Troubleshooting

If the IPSec tunnel does not build properly, the problem is likely a configuration error at one of the IPSec routers. Log into the web configurators of both ZyXEL IPSec routers.

Check the settings in each field methodically and slowly.

VPN Log

The system log can often help to identify a configuration problem.

Use the web configurator LOGS Log Settings screen to enable IKE and IPSec logging at both ends, clear the log and then build the tunnel.

View the log via the web configurator LOGS View Log screen or type sys log disp from SMT Menu 24.8. See Appendix S on page 770 for information on the log messages.
