Sv getrealip
From FTE
Safer way to retrieve the true IP of clients.
1 (secure) = Stuffs the client to send a packet back to the server and thus determines the IP from that. 2 (very secure) = The server will also send an A2A_PING to the retrieved IP and expect A2A_ACK back. 3 (extremely secure) = Will also require a challenge.
