Why would an active firewall in an active-passive HA configuration broadcast gratuitous ARPs every 60 seconds?

I found a KB article stating that the active firewall sends out gratuitous ARPs every 60 seconds during normal operation, but it doesn't explain why. What is the reason for this behaviour? https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u0000004Ny3CAE

HA failover on Acitve Passive concerns

Hello all, I would like to get some idea/thoughts about the current setup on my two PA1410 Active/Passive FW failover concerns. Few weeks ago, our Active FW has some issues and hung on the data plane. I found there was some missing configurations on our network side so the Failover didn't work at all. So eventually I resumed it, and raised the...

Intrazone-default Rule

I have a question and would like some advice! We currently operate by applying an “any-any deny” policy at the bottom of the stack and opening ports only for necessary traffic.I noticed that the hit count is increasing on the “intrazone-default” allow policy at the bottom, even though the “any-any deny” policy is in place.I enabled logging for t...

Decryption policies and Short-Lived Certificates

Hi All, So basically, certificate validity will be shortened gradually until it is down to 47 days. The prospect of importing and reconfiguring our decryption policies that often is not very appealing. The problem i see is that, while we can automate certificate renewal on the servers, and the actual import process using CLI/API, there's sti...

Resolved! Unable to find "Hide My IP" application on firewall (Applipedia shows it exists
