# NAT Rating #### 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
