General Discussion / Re: Suddenly blocked within LAN by Default deny / state violation rule

There's something you're not telling us about your setup. Post pics of your network layout.
Thanks Demusman
Attached the network situation. All IPs manually an in Subnet 255.255.255.255. Router and DNS-Server 192.168.1.1.
All you see on this layout has been worked well many months. Regular updates on the iMac and OPNsense. I have the feeling that either the Mac OS 12.6.1 > 2 > 3 Update or the last few OPNsense updates are causing my problems. Updating OPNsense today onto 23.1_6 was not solving.
Again, if I switch the iMac onto WLAN via the Timecapsules AP there is all green in the firewall live log.
Thanks again for any help.
