OSPF Dropdown Lists aren't stable after Updating to 2.4.2
I didn't know where to put this. It is nothing significant. After the upgrade from 2.2.X versions to 2.4.2 the Quagga-OSPF configuration is actually getting a bit messy.
At first I thought it is only the OSPF CARP Status IP drop down list is getting resetted. But I have just realized that all of the drop down lists are changing the chosen one. The issue is both on Global settings and on the Interface settings. I can see the interfaces are reordered randomly between each of the interface configurations. I had to tidy it back to its proper config, which takes a few minutes only but I guess this is something to be fixed.
Do you think this has happened because of upgrading from very old pfsenses?
Nothing that significant changed in the package from 2.2.x to 2.4 that would cause problems as you describe. Maybe you have a browser cache issue or script blocker that is interfering.
