Also, in Security Zone filed, you need to select the security zone as defined in Step 1.

To define the tunnel interface, Go to Network > Interfaces > Tunnel.Select the Virtual Router, default in my case. You need to define a separate virtual tunnel interface for IPSec Tunnel. In the example below we are leveraging the intrazone-default rule, and this rule will allow both the IKE negotiation traffic ( untrust to untrust) and the encryption domains traffic ( trust to trust). Creating a Tunnel Interface on Palo Alto Firewall. However, if we have a deny rule on top of the intrazone-default rule, or if we have overridden the intrazone-default rule action to deny instead of allow, then we need to create a couple of rules to allow the IKE negotiation traffic and the encryption domains traffic between the Palo Alto and ASA firewalls. This means that if we are leveraging the default rule intrazone-default which by default will allow the traffic traversing within the same zone, then we don't have to add any security policy to make our VPN tunnel functional. All information travelling from a device connected to a VPN will get encrypted and go through this tunnel. Similar for the traffic between the encryption domains, in our case both the local encryption domains interface and remote encryption domains interfaces ( tunnel.1) belong to the same security zone, trust. How Does VPN Work A VPN creates a private connection, known as a tunnel, to the internet. The IKE negotiation traffic between the Palo Alto and the ASA will be traversing within the same zone, in our case, it will be sourcing from untrust destined to untrust. We are not officially supported by Palo Alto Networks or any of its employees. This subreddit is for those that administer, support or want to learn more about Palo Alto Networks firewalls.

The interzone-default rule instead is used for the traffic traversing between the zones, for example, between trust and untrust, and this rule is set to Deny action by default. Hi Team, I ve configured GlobalProtect VPN using How to configure GlobalProtect VPN in Palo Alto Firewall guide. The intrazone-default rule is used for the traffic traversing within the same zone, and it is set to Allow action by default. ISP1 is used as the primary ISP on Ethernet1/3. This setup is frequently used to provide connectivity between a branch office and a headquarters. Palo Alto firewalls have a couple of default rules, one is the intrazone-default and another is the interzone-default. This document explains how to configure a Palo Alto Networks firewall that has a dual ISP connection in combination with VPN tunnels. The security policies configuration for the VPN tunnel depends on our existing security policies.
