Redirecting an ip in Java
ip, java, proxy, redirect
Solution
Redirection of connections along the lines that you want requires support from the (application) protocol. TCP/IP does not support it. AFAIK, SOCKS does not support it either. Unless the Minecraft application protocol (and by implication, Minecraft clients and servers) include support for redirection, you are out of luck.
(FWIW - that's how HTTP redirection works. HTTP has a "protocol element" that allows the server to tell the client to redirect, and where to redirect to. The client then resends the original request to a new address.)
But that doesn't mean that you can't deal with the pests. It just means that the redirection approach is not viable. Try a custom proxy or an IP filter / redirector instead.
Problem
For the past few weeks, I have been scouring the internet, the minds of computer programmers, and just a few random people over the situation I am looking to overcome. Basically, what I am trying to do it write a AntiJoinBot "plugin" (if you will) for the popular game Minecraft. This would be like all others in respect that it blocks IPs based on if they are using a proxy or not, but this AntiJoinBot is running on a different VPS than the actual server. This is the best graph I can make of the situation (it's not that good): (non-minecraft server) Connection -> Proxy check -> Redirect to the server -> Minecraft The only problem is, I need to be able to redirect the IP and close the connection so that the player's real IP is the one that would connect to the server. If the connection is not able to be closed, it would cause real problems due to some of the plugins we are running. If you have a solution or a better way to do this, please help me.
