@Astator it's a harmless message, happens on linux too if not allowing incoming connections from firewall (and maybe even doing some extra steps on the router for port forwarding) you're synced up so it's fully working already, you can mine, access your wallet, send / receive wowneros allowing incoming connections would help support the network by being a public facing full node if you leave it up online 24/7, but if just opening the thing once in awhile then it's not necessary to allow incoming connections to use the thing and often having services hosted on home network might bloat the connection or add attack surfaces or things like that, as opposed to hosting it on a vps which is more fit to host public facing services
