If I'm with a small-time ISP that has to use CG-NAT because they don't have the cash to buy/lease enough IPv4 addresses to give one to each CPE WAN interface, then using things like Xbox/PS multiplayer/P2P gaming is no longer possible. Want to host a Minecraft server? Too bad.
Are those two use-cases "useful to the consumer"?
I did port forwarding in 2010 for a Minecraft server. Basically every router supports it.
It wasn't meaningfully more difficult than setting up the server.
You are right, but ISPs will tell you that you're not allowed to host servers anyway. Most have it in the AUP.
