Interface IP address configuration when firewall in HA active passive

[ismailsh]

Hi,

I have 2 palo alto firewalls configured as active and passive.  I want to know how I should configure the Interface IP address (for inside and Dmz) on the passive firewall?  Do they have different IP address configured from the active firewall (similar to how we do it on Cisco ASA) ?

Thanks

@ismailsh,

You don't configure interface addresses on the passive firewall when you have an Active/Passive pair. The configured interface address(es) will only ever be active on the Active firewall. You'd access the Passive firewall by its MGMT port and it's configured IP address.

Hi BPry,

Thank you for your reply.  When I tried to remove the IP address from the passive firewall using Panorama config deploy , panorama config deploy errored out.  Therefore I put the same IP address that I have on the active Palo Alto onto the passive palo alto.  Once I deployed the configuration (with both firewalls having the same inside IP) , I did a failover test and it was successful.

Active/Passive firewalls should be inside same template in Panorama.

Hi @ismailsh ,

Fun fact for Panorama managing HA firewalls - Panorama always push the configuration separately to both members when they are in active/passive mode.
