For NAT concepts and all available methods, refer to:
1. Enable Network Discovery
Open Settings
Go to Network & Internet
Select Advanced network settings
Enable Network Discovery
Ensure your network is set to Private
2. Check Windows Firewall
Allow the node through firewall
Ensure UDP traffic is not blocked
Restart the node after changes
3. Apply router-level fixes
If NAT is still Strict, configure your router:
Enable UPnP
Or use port forwarding
Or use DMZ (last resort)
Refer to the main NAT guide for details.
