[MERANA]

if I have a shared policy and if i map different zones for both Gateways using the same policy base. is it going to work?

Yes.

When sharing a policy package across two firewalls, all referenced zones/interfaces (ADOM interfaces) must exist on all target firewalls.

So you can map a zone called "public" to different interfaces on different firewalls. But if the policy package references "public" in firewall rules, then "public" must exist and be mapped accordingly on both.
