IPSec Debug
If you are having difficulty building an IPSec tunnel to a non-ZyXEL IPSec router, advanced
users may wish to examine the IPSec debug feature (Menu 24.8).
Note: If any of your VPN rules have an active network policy set to nailed-up, using
the IPSec debug feature may cause the ZyWALL to continuously display new
information. Type
ipsec debug level 0 and press [ENTER] to stop it.
