Guide 16: UPnP & Port Forwarding — Achieving Open NAT for Seamless Peer Connections
Eliminate Moderate/Strict NAT warnings and voice chat packet drops on PC and consoles.
Universal Plug and Play (UPnP) allows gaming applications and voice clients to dynamically request port openings on your router's firewall. Without open ports, multiplayer matchmakers struggle to negotiate direct peer-to-peer audio and game state synchronization.
Configuration Guidelines
Ensure UPnP is set to Enabled in your router's Advanced / Firewall settings. If certain competitive games still report "Strict NAT", configure static IP DHCP reservations and set up dedicated manual Port Forwarding rules for UDP ports 3074, 3097, and 27015-27030.
