Describe the feature request

Forward User IP through Server to Client for UDP, and other protocols.

Instead of client showing 192.x168x.x:xxxx for each user, show real IP and ports used from server connection.

This will enable me to:
1: Collect Data / Regional Connection Data from UDP connections
2: Be able to Permanently Ban IP's from UDP connections

Describe alternatives you've considered
