Making A Server Accessible From Any Network.

Suggestion: Make a hub/server with either port 8080 or 443
Reason: those are commonly possible to access from every possible network, we have a network that blocks every possible port except some whitelisted ones and playing wynncraft would be super cool without needing to use phone network or vpn.

 

This is a decent suggestion, however here are my concerns:

Minecraft standard uses port ranges that fall within typical "video game server" port ranges (25565 is an example port). Typically ISPs' highest firewall settings (or modem/router firewalls too) will block "video game server" connections. This means that basically any sort of game server will be blocked by your network's firewall.

A port like 443 is used for HTTPS protocol and 8080 typically HTTP protocol. While it's possible (and I don't see the harm) to use those ports for packet flow, Minecraft uses neither of them and recommends you don't. Especially since this is a game server the last thing we want are web crawlers sniffing those ports which could down the network if not handled properly.

Many ISPs and routers' firewalls have settings that can unblock game servers but still block other ports. You could also manually configure this (of course with parental permission if that applies). I have my configured my home network to do just that (and I have Comcast).

Additionally, not many people configure their firewall this way and I don't think it's gonna change.

Finally, it is quite a cost to boot/host a proxy server to serve a small niche of people. It's not like we pay X USD and bam! It's up and running. It would have a very different configuration, would require manual modification (to communicate with other proxies/main servers + manage potential web packet types which could theoretically overflow and crash the server if flooded), and would require additional maintenance that looks different from typical game server maintenance.
