It all depends on the number of zones, you have used. Usually the following
is the way ZFW is configured:


inside ---------------- in zone Router out zone -----------------------
Outside




in to out zone > inspects traffic from inside to outside and allow them back
self to out > inspects router generated traffic
out to self > Allows traffic coming to router



IPSec traffic will terminate on the router and after decryption the clear
traffic should pass out zone to in zone.Hence we should configure out to
self zone accordingly.

out to self > Allow ESP, AS, ISAKMP and Non-ISAKMP with pass action. You
can't use inspect as ZFW can't inspect these protocols except non-ISAKMP
which uses UDP.

While clear traffic is encrpted, the self to out zone should permit the VPN
traffic

self to out > Either use pass action for class-default or have a class for
AH, ESP, ISAKMP and Non-ISAKMP with pass action

To allow the clear text back:

Out to in > Should allow the client network for clients in network extension
mode and the leased pool network for clients in client mode
