How will threat functionality work with asymmetric routing

L3 Networker

Posted this on threat discussions but havent had any responses. Please help me understand what will happen in this case.


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.

If you need asymmetric routing then set up active/active HA.

In this case packets of same session will be forwarded to firewall that is owner of this specific session so it can check all of them and provide better protection against threats.
