After update got no internet on main lan and few minutes later the vlan also got the same issue I Was able to fix it with a backup I made few weeks ago fortunately fist time got this problem. kind of scary!
And what was the issue, what was different in the configs? Just in case someone else got the same or similar issue?
Although I saved a config-opn after the no internet, I just reloaded (same issue) and did not notice any difference in Firewall/ rules with my working config.
I can just assume it got corrupted during the update, and it does not mean it going to be the same for everybody, but just to be on the safe side I would recommend a back-up before any upgrade.
Do you happen to have any firewall rules involving the bogons alias? Either the alias or how it's interpreted seems to have changed.
