Neuron P2P Diagnostics v1.0.2 - Fixed NAT Detection
🔧 Update v1.0.2 - Fixed NAT Detection
🐛 Bug Fix
- ✅ Fixed NAT Detection: Resolved critical issue where NAT test always reported 'No NAT'
- ✅ Proper Local IP Detection: Now correctly detects private IP addresses (192.168.x.x, 10.x.x.x, etc.)
- ✅ Accurate NAT Classification: Properly identifies NAT types (Restricted Cone, Port Mapping, etc.)
- ✅ Port Mapping Detection: Now correctly detects when local port != public port
What Was Fixed
The NAT detection was failing because was nil, causing the logic to incorrectly assume a public IP. Now:
- Properly retrieves local IP from UDP connection
- Correctly identifies private IP ranges
- Shows accurate NAT type and port mapping status
Example Output (Before vs After)
