For sanity check, can I fresh install the latest version and then import the settings via backup file considering I'm running v25.7.11_9 ?
Anything to be aware of?
Tia.
Possibly you need to install the ISC DHCP plugin if you are using ISC at the moment and have not yet migrated to a different DHCP service.
Thanks, and will I have to tweak/change any of the firewall rules at all (including NAT, port-forward/outbound)?
I upgraded to 26.1.4 overnight (though I was already on 26.1.x previously). I did notice that all my permitted networks lost Internet post-upgrade. All the Firewall rules were correct and had not changed. I hit the solution by removing my WAN Gateway entry and re-creating it, even though I didn't change any of its settings.
