Well I have something i'd like to see in the web console. Only one game server host does this, but I've found one that offers customers to have access to the firewall in the control panel. I haven't used it before, but it would really help for some older games like quake and others cause the banning features are really limited in those games and some exploits allow people to get around bans.

Hm, controlling a hardware level item like the firewall probably isn't going to be something that is controllable by the user anytime soon unfortunately. If a block is needed it can be put in manually.

Having said that, blocking IPs in this manner (like blocking a person from connecting) is something that can be routed around using proxies very easily.
