How will threat functionality work with asymmetric routing

L3 Networker

I would like to understand what will happen to Threat Protection and AntiVirus(TPAV) in the following case.  Both firewalls have "allow" non-syn-tcp turned on. Each firewall is only seeing half of the session and has no idea about the other half. 


My questions is will Palo be able to detect any threats or vulnerabilities, (or) does it need to see a bi-directional flow/session to kick in TPAV parameters.


Please let me know for any questions in case I am not clear.

Is there a reson you are not running HA? Doing this might resolve your issue and keep your network flowing correctly.

The way it's currently implemented, it won't be able to detect threats.

You need to change the configuration to Active-Active HA, this is the scenario that Active-Active is designed to resolve.
