In 22.7 I had a rule that allows all IPv4 from 'Lan Net' to 'Lan Net' , but after update to 23.1 the multicast traffic from my DLNA server is blocked and I had to create a new rule: allow ipv4 udp from <DLNA IP>:57953 to 239.255.255.0/24:1900.
Any reason for that change ?
I'm pretty sure multicast was never included.
Cheers,
Franco
