My kids used to play Minecraft with their friends over LAN with tablets, but we moved. I can set them up with xBox live accounts, but ideally I would like to replicate the single world over LAN where they are playing in a world with just these friends. The goal being to prevent them from interacting with unvetted strangers online. While I could potentially try to setup server, I am the only one in the household that could troubleshoot it, and I don't need the headache of a home server not working when I am not available.
I see there are a lot of similar questions here, but the answers I see are assuming that all players are on a PC, and tend to discuss downloading a popular VPN exe. My kids and their friends are on tablets a mix of iOS and Android.
Thoughts on how to create these limited worlds to play over the internet?
