Security Policy for IPSec traffic

Farzana — Wed, 28 Dec 2016 00:59:07 GMT

Hello,

We are setting up Site-to-Site IPSec VPN between PA and Cisco router. The examples provided on PA websites do not suggest any security policy for this. When we use a security policy for 'Outside-Untrust' to 'Outside-Untrust' to allow traffic between IPsec tunnel end points, we can see traffic matching this policy.

Do we need an intrazone policy on 'Outside-Untrust' just for IPSec traffic?

First you have to allow IPSEC traffic (IKE, ESP...) between (public) IP addresses of both VPN peers.

Then you have to make rules which traffic to allow througfh VPN (between networks/hosts defined in proxy IDs). Security zones is usually between LAN/trust/internal and zone that you associated with the tunnel interface for that specific VPN.
