[SOLVED] The backup firewall is not accessible or not configured

[andrema2]

Hi all

I have a HA setup working for more than an year. Today I realized that the HA Status is giving this message "The backup firewall is not accessible or not configured." It was not like that before.

I can ping each FW from each other using the SYNC interface. There is a direct cable between the two FW.

I rebooted both FW and the issue still happens. Not sure what else can I do.

Adding more information.

I changed the IP address from both SYNC interfaces. Then when I tried to change the IP address of the slave on the High Availability Settings page it doesn't stick. I push save it refreshes and the old IP comes back. I can change the synchronize interface and it does stick. I tried with 3 different browsers to make sure it's not the cache with the same results.

I also tried to clean the field and leave it blank but the old IP comes back.

On the slave FW everything works as it should. I was able to change and save the configuration.

I reseted to the defaults and restore the config but the issue remained

What are your firewall rules on that sync interface?

I saw your other post and realized that I had the same issue. Once I allowed the SYNC interface everything was ok
