14.11 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 (in the commands).

"

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.
