LAN web GUI no access

[cookiemonster]

quick look at your screenshots you have blocked access from LAN via the disabled rule and allowed it only from aliased sources. You need to diagnose that setup and I can offer no explanation why it was working before and not after the update. Was it rebooted post upgrade by the way? Maybe stalled sessions.
To diagnose you will likely want to temporarily enable logging that is currently disabled, like default blocks.

>Only I can access the firewall now outside the company through the WAN port which I already make it open to remote setup and configure the firewall from the web interface.
I guess at least you have a way to manage it still but I hope you know what you're doing there.
