Firewall4 / NFtables Tips and Tricks

Installing and Using OpenWrt Network and Wireless Configuration

I've noticed that saving and applying changes in LuCI doesn't work if I don't restart the firewall service. Some rules don't work either.

This rule does work:

config rule
        option name 'AdGuardHome para invitados'
        option src 'invitados'
        option dest 'lan'
        list dest_ip '192.168.1.11'
        option dest_port '53'
        option target 'ACCEPT'

But not this one:

config rule
        option name 'Bloquear servidores DNS externos en invitados'
        option src 'invitados'
        option dest 'wan'
        option dest_port '53 853'
        option target 'DROP'
