Resolution


This document describes how to configure a dual ISP for a branch office.  In this scenario, an office is connected to two ISPs with redundancy for outbound connectivity. This configuration uses a combination of static routing, policy-based forwarding (PBF), and destination interface-based source NAT translation. The solution provides automatic outbound internet redundancy without requiring BGP routing protocol between ISPs.

 

Note: This document has been modified for PAN-OS 5.0 and later.  Multiple external zones are no longer required.
