STUN P2P Connectivity Test

Test if your network supports peer-to-peer file transfers

Quick Connectivity Test

Check if your network can establish direct peer-to-peer connections using STUN.

Understanding NAT Types

✅

Full Cone NAT

Best case scenario. Any external host can send packets once you've sent one packet to any destination.

Works with: Everyone

✅

Restricted NAT

Good compatibility. External hosts can send packets only if you've previously sent to their IP.

Works with: Most networks

⚠️

Port Restricted NAT

Moderate compatibility. Requires matching both IP and port from previous outbound connection.

Works with: Some networks

❌

Symmetric NAT

Poor compatibility. Uses different ports for each destination. Common on cellular networks.

Requires: TURN relay

Common Network Scenarios

🏠 Home WiFi

Usually works great! Most home routers use Restricted or Port Restricted NAT.

If it fails, try restarting your router or checking firewall settings.

📱 Mobile/Cellular

Often uses Symmetric NAT. May have trouble with P2P connections.

Try switching to WiFi for better compatibility.

🏢 Corporate Network

May block P2P entirely or use Symmetric NAT for security.

Consider using a personal hotspot or home network.

🎓 University Network

Policies vary widely. Some allow P2P, others restrict it heavily.

Check with IT department about P2P policies.
