@steveits said in Any pfBlocker issues with Upgrade from 2.4.5 to 2.5.x?:
Netgate recommends removing packages
I like to add :
When all packages are removed, reassure that basic firewall operations are good. Add a 24 hours cool down and one or two reboots are also advisable. Issues that are present before an upgrade will pop up, and have to be dealt with before the upgrade.
