How does that even work?
The auth server tells the client it's IP as a part of the initial auth.
function authTCPobj_Client::onLine(%this, %line)When the client receives a line of data from the TCPObject that handles authentication,
if (%word $= "YOURIP").. if the first word of the line is YOURIP
$MyTCPIPAddress = getWord(%line, 1);.. set the global variable.
