Pro NAT & Port Diagnostics

Professional-grade network diagnostics for cloud gaming — detect your true NAT type and validate port forwarding instantly.

Home Reboot your router after applying port forwarding rules to flush stale NAT tables.

NAT Intelligence

Detects your precise NAT category: Full Cone, Restricted Cone, Port-Restricted Cone, or Symmetric — using multi-STUN server analysis.

Recommendations

  • Initiate a scan to receive tailored advice.
NAT Type Reference Guide
Full Cone (Open) Any external host can send packets to your mapped port. Best for online gaming. Equivalent to PlayStation "Type 1" / Xbox "Open".
Restricted Cone (Moderate) Only hosts you have previously contacted can reply. Acceptable for most games. Equivalent to PlayStation "Type 2" / Xbox "Moderate".
Port-Restricted Cone Similar to Restricted but the source port must also match. Can cause issues in some P2P games and party chat.
Symmetric (Strict) Each destination gets a different mapped port. Hardest NAT to traverse. Equivalent to PlayStation "Type 3" / Xbox "Strict". Requires port forwarding or UPnP to improve.

Port Availability Suite

Batch-test essential cloud gaming ports via external probe. Apply presets, enter custom ranges, and confirm forwarding rules instantly.

Leave blank to auto-detect. Or enter any hostname / IP for a targeted scan.

Comma-separated. Ranges: 27015-27030. Append /udp for UDP. Max 20 ports per scan.

Advanced Router Config — Quick Guides

Compact explainers to help you unlock Open NAT, master port forwarding, and prioritise gaming packets.

Open NAT Playbook
  • Assign a static IP to your console or gaming PC before applying port rules.
  • Enable UPnP for automatic port negotiation when available.
  • If your router supports it, activate "Full Cone NAT" or "NAT Acceleration".
  • Avoid double NAT by using bridge mode on secondary routers.
Port Forwarding Blueprint
  • Forward both TCP and UDP ranges to the device IP.
  • Use consecutive port ranges to simplify firewall rules.
  • After saving rules, reboot the router to clear stale NAT tables.
  • Verify open ports using this tool and in-game network tests.
DSCP Tagging & QoS Enhancements
  • Mark gaming traffic with DSCP EF (46) or CS6 priority where supported.
  • Pair DSCP tagging with Smart Queue Management (SQM) to tame bufferbloat.
  • Allocate at least 30 % reserved bandwidth to gaming devices during heavy use.
  • Regularly update router firmware for the latest QoS improvements.
Fixing Symmetric NAT
  • Check if your ISP uses Carrier-Grade NAT (CGNAT). If so, request a public IP.
  • Enable port triggering or DMZ (temporarily) to validate the issue.
  • Some routers allow configuring "NAT type" directly — look for Full Cone or Endpoint Independent options.
  • As a last resort, a VPN with a static IP can provide a stable NAT environment.
