NAT Rating$M_N$

The NAT (Network Address Translation) type directly affects connection quality and stability. Therefore, corresponding credit rewards have been set for different

NAT types:

Public Network IP = 1.5

NAT 1 = 1.4

NAT 2 = 1.3

NAT 3 = 1.1

NAT 4 = 1

Additional Information about NAT:

NAT1: Full Cone NAT is the most lenient network environment with virtually no restrictions on IP and port usage.

NAT2: Address-Restricted Cone NAT imposes restrictions on IP addresses compared to NAT1 Ports remain unrestricted.

NAT3: Port-Restricted Cone NAT imposes restrictions on both IP addresses and ports compared to NAT2, meaning both the IP and port are restricted.

NAT4: Symmetric NAT is characterized by restricted port cone-like properties, where each internal address request to a specific external address may be bound to a new port number. In other words, the port number mapped to different external addresses may vary. This form of NAT essentially says goodbye to P2P.
