I understand from the guide that this isn't recommended, but that it is supported. I've managed to complete the deployment without any issues.</P> <P>However, I have some questions. Since it’s not possible to move an ENI between AZs, if there’s a failure with FW-A or AZ-A, FW-B will be active, but traffic will still be routed to A. How can I resolve this issue?</P> <P>The reason for this architecture is that I want session synchronization, and I want both firewalls to synchronize without needing Panorama.</P> <P>Is there a guide that can help me resolve this issue?</P> Mon, 27 Jul 2026 22:26:08 GMT https://live.paloaltonetworks.com/t5/vm-series-in-the-public-cloud/ha-fw-on-aws/m-p/1260075#M2470 D.Villanueva403262 2026-07-27T22:26:08Z Re: HA FW on AWS https://live.paloaltonetworks.com/t5/vm-series-in-the-public-cloud/ha-fw-on-aws/m-p/1265996#M2483 <P>Hi&nbsp;<a href="https://live.paloaltonetworks.com/t5/user/viewprofilepage/user-id/315085657">@D.Villanueva403262</a>&nbsp;Did you followed all the steps give <A href="https://docs.paloaltonetworks.com/vm-series/deployment/public-cloud/set-up-the-vm-series-firewall-on-aws/high-availability-for-vm-series-firewall-on-aws/configure-activepassive-ha-on-aws-secondary-ip" target="_self">here</A>?</P> Mon, 12 Oct 2026 14:51:11 GMT https://live.paloaltonetworks.com/t5/vm-series-in-the-public-cloud/ha-fw-on-aws/m-p/1265996#M2483 SutareMayur 2026-10-12T14:51:11Z
