Just allowing inbound connections from any external host on well-known port ranges (like a game) is bad and should NOT be default.

It's basically a DMZ or full range port forwarding for all devices in the LAN.

Just set a DMZ or full-range port forwarding for your console(s), it's still unsafe, but at least it's just for the console and not everything else in the LAN too.

It is a feature that is necessary and should be by default in OpenWrt.

I hope you will add it in the next releases or at least the package.

Thank you.

    I am all for exposing Cone Nat in UCI / Firewall zones as an option
    to the masquerading configuration in a zone.

    Also as much as I hate it nat66 for IPv6 needs to be exposed in the
    same place - specifically for mapping routable PD which change often
    to ULA's.
