udp 22124 jamulus server port doesn't work

[openasapce]

Hello.
where I'm wrong?
opening udp port 22124 for jamulus server results in connection deny in the logs.

I have set,
from: wan address
destination: this firewall
source port: any
destination port: 22124
lan address: 192.168.30.101
destination: 22124

In vpn (local remote opnsense lan) I can connect to the jamulus server but using wan ip.. I see connection drops in the logs..
others tcp rules are working correctly.

thanks.
