Newer devices might support the Port Control Protocol, so applications can ask for the port to be forwarded on ipv4 and allowed in the firewall for ipv6



Which does not solve the common case when you want to pass unfiltered ingress trafic to few specific hosts and have the default reject unknown ingress behavior for all other LAN hosts. Just give me the ability to set my own firewall rules when I need to instead of drop-all/drop-ingress/accept-all combo-box with confusing label.
