This router distribution really needs a UPNP feature

i have a lot of trouble getting some ports open and stuff learning what is need for different games etc on xbox, and some other things look for a UPNP router to hand there requests, this is missing such a in my opinion must needed feature, i know its not safe and all that but it could simply be good to even just allow certain ips to assign to it to allow upnp from them,
i will donate real money to get this feature added as standard or even a plug in, must be something, i hope nethserver gets it on as standard feature
its standard on pfsense

It seems something not so hard

found a upnp lan test software to confirm upnp function is working and as expected it failed but this could be used to help with the testing it runs on Java
