TCP/UDP port mapping for full cone NAT

NATMap project is used to establish a TCP/UDP port mapping from ISP NAT public address to local private address. If all layers of NAT are full cones (NAT-1), any host can access internal services through the mapped public address.

• Transparent Port forward (Forward port = 0)
• Refresh the listen port of the BT Client (Forward port = 0)
• Port update notify script
• A Record update script
• AAAA Record update script
• SRV Record update script
• HTTPS Record update script
• SVCB Record update script
