Zone Forwarding not working

This is my configuration in Luci:

but LAN and TELEFONIA don't connect to each other.
I suspect is a VLAN problem, but in 19.07 it worked with the same exact configuration.
I tried a lot of things but with the only results of cutting myself out of the router.

any suggestion will be appreciated.
I'm for sure missing something obvious.
