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
SMT Menu 24.8. See
Appendix I VPN Setup
