Hello all,   I am using the guide below to clear out UDP sessions after a PBF failover.  When I get to the part about the key parameter under Payload Format, it says the value is too long.  I am copying the exact key I generated from the web browser.  The key generated is 132 characters, but it says the max length is only 128 characters.  The firewall is running 9.0.14-h4.  Am I missing something?   https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u000000HBmqCAG&lang=en_US%E2%80%A9 ...

Good morning everyone,   I have a weird issue that I think is related to how PBR or NAT works and/or something we need to program differently on our Palo Alto. I’ll try to explain our setup and the issue that occurred.   We have our main circuit that is utilized for VPN tunnels, NAT forwarding rules to our servers and pretty much anything that is not standard Internet traffic. We’ll call that Circuit A.   We have another circuit used for mostly standard outbound Internet traffic for certain VLANs. This is also the circuit that our DNS servers use for requests. It is high bandwidth but it is not a business class circuit with SLAs so it is not used for critical applications. We’ll call that Circuit B.   Like it was stated above, all NAT forwarding rules use Circuit A with the exception of one server (let’s call it Server 1) where we have a NAT forwarding rule that uses Circuit B. Note that this server is in a VLAN that uses Circuit A for outbound traffic.  This server also has several internal IP addresses associated with it and they all use Circuit A for outbound.  The NAT forwarding rule only points to one of these internal IP addresses.   Last night the ISP did planned maintenance on Circuit A which took it completely down. When this happened the NAT forwarding rule to Server 1 (which again goes over Circuit B) stopped working. My current guess is that somehow even though the NAT forwarding uses Circuit B to Server 1 it somehow uses Circuit A for outbound on this rule maybe on one of its other assigned internal IP addresses. I didn’t think NAT would work like that but nothing else comes to mind as to why the NAT forwarding rule to Server 1 over Circuit B would stop working. Any thoughts? Hopefully my explanation on our setup wasn’t confusing but if clarification is needed please let me know.  Thanks! ... View more
