[Solved] 22.7.4 High Availabilty

[ednt]

I wanted to update our Master/Slave combination from 22.7.4 to 22.7.8 and, as always, I tried a
synchronisation from master to slave.

But ...

The backup firewall is not accessible or not configured.

No idea what's wrong.
I can ping the slave on the PFSYNC interface and I see also traffic with tcpdump on the slave.
But I see no listener on the slave network interface.

Then I updated the slave to 22.7.8, but still the same.

How can I check or start the service on the slave side?

Did you change the Interfaces setting for the UI?

System > Settings > Administration

You saved my day!

I had to add the PFSYNC interface, which is used for the High Availability, to the allowed interfaces for the Web-
GUI.

But we used the HA sync since ages with no problems in the same configuration.

Anyway,

thank you for this hint.
