We have deployed Palo Alto VM-Series firewalls in Azure in Active/Passive mode. When the active firewall fails, the passive firewall successfully becomes the active one. This behavior is reflected correctly in both the firewall interface and the floating IPs within the Azure portal, and the traffic flow is unaffected during this transition.
However, when a failover happens back to the original active firewall, although the floating IPs and firewall status reflect the change correctly, there is a disruption in traffic flow for approximately 8-10 minutes before it resumes.
Could you please assist in identifying the cause of this delay and help resolve the traffic disruption during the failover process?
