A minecraft modpack that adds nothing - including accessibility improvements, character customization, rebalanced difficulty, and a fully in-game tutorial for vanilla. On modrinth at: https://modrinth.com/modpack/tinkerers-quilt
That mod uses a third party listen server out of any user's control, not NAT punchthrough. if it works for you, definitely use it in your own instance.
I find that mcwifipnp requires that I change my network settings, and World Host works ootb https://modrinth.com/mod/world-host
