So basically what I am trying to do here is run two different severs on the same IP address but different ports, but the problem I am getting is this message that says "SocketException: Only one usage of each socket address (protocol/network address
/port) is normally permitted.". I really don't know what that means or how to fix it, if anyone on here is familiar with this error and knows how to fix it please telll me, players on my community really want this second server.

its very easy to run 2 servers on one ip
open 2 ports on your router and set each server to have a different port.
Looks like you trying both on same port.
