NAT类型测试工具（NatTypeTester）

资源内容介绍

NatTypeTester用于帮助用户检测和理解他们的网络连接类型。该项目基于Python语言编写，简单易用，并提供了一种直观的方式来识别你的网络是NAT类型还是直接连接，这对于进行网络诊断、游戏优化或P2P应用开发等场景尤其有价值。NAT类型一般分成下列4种：　　1. Full Cone NAT （彻底圆锥型）　　2. Restricted Cone NAT （详细地址限定圆锥型）　　3. Port Restricted Cone NAT （端口号限定圆锥型）　　4. Symmetric NAT (对称性型)

Furthermore, any external host can send a packet to the internal host, by sending a packet to the mapped external address. </summary> </member> <member name="F:STUN.Enums.NatType.RestrictedCone"> <summary> A restricted cone NAT is one where all requests from the same internal IP address and port are mapped to the same external IP address and port. Unlike a full cone NAT, an external host (with IP address X) can send a packet to the internal host only if the internal host had previously sent a packet to IP address X. </summary> </member> <member name="F:STUN.Enums.NatType.PortRestrictedCone"> <summary> A port restricted cone NAT is like a restricted cone NAT, but the restriction includes port numbers. Specifically, an external host can send a packet, with source IP address X and source port P, to the internal host only if the internal host had previously sent a packet to IP address X and port P. </summary> </member> <member name="F:STUN.Enums.NatType.Symmetric"> <summary> A symmetric NAT is one where all requests from the same internal IP address and port, to a specific destination IP address and port, are mapped to the same external IP address and port. If the same host sends a packet with the same source address and port, but to a different destination, a different mapping is used. Furthermore, only the external host that receives a packet can send a UDP packet back to the internal host. </summary> </member> <member name="T:STUN.Enums.StunMessageType"> <summary> This enum specifies STUN message type. </summary> <returns> https://tools.ietf.org/html/rfc5389#section-6 </returns> </member> <member name="F:STUN.Enums.StunMessageType.BindingRequest"> <summary> STUN message is binding request. </summary> </member> <member name="F:STUN.Enums.StunMessageType.BindingResponse"> <summary> STUN message is binding request success response. </summary> </member> <member name="F:STUN.Enums.StunMessageType.BindingErrorResponse"> <summary> STUN message is binding request error response. </summary> </member> <member name="F:STUN.Enums.StunMessageType.SharedSecretRequest"> <summary> STUN message is "shared secret" request. </summary> </member> <member name="F:STUN.Enums.StunMessageType.SharedSecretResponse"> <summary> STUN message is "shared secret" request success response. </summary> </member> <member name="F:STUN.Enums.StunMessageType.SharedSecretErrorResponse"> <summary> STUN message is "shared secret" request error response. </summary> </member> <member name="T:STUN.Messages.StunAttribute"> <summary> https://tools.ietf.org/html/rfc5389#section-15 </summary> </member> <member name="M:STUN.Messages.StunAttribute.TryParse(System.ReadOnlySpan{System.Byte},System.ReadOnlySpan{System.Byte})"> <returns> Parse 成功字节，0 则表示 Parse 失败 </returns> </member> <member name="T:STUN.Messages.StunAttributeValues.AddressStunAttributeValue"> <summary> https://tools.ietf.org/html/rfc5389#section-15.1 </summary> </member> <member name="T:STUN.Messages.StunAttributeValues.ChangedAddressStunAttributeValue"> <summary> https://tools.ietf.org/html/rfc3489#section-11.2.3 </summary> </member> <member name="T:STUN.Messages.StunAttributeValues.ChangeRequestStunAttributeValue"> <summary> https://tools.ietf.org/html/rfc5780#section-7.2 </summary> </member> <member name="T:STUN.Messages.StunAttributeValues.ErrorCodeStunAttributeValue"> <summary> https://tools.ietf.org/html/rfc5389#section-15.6 </summary> </member> <member name="T:STUN.Messages.StunAttributeValues.MappedAddressStunAttributeValue"> <summary> https://tools.ietf.org/html/rfc5389#section-15.1 </summary> </member> <member name="T:STUN.Messages.StunAttributeValues.OtherAddressStunAttributeValue"> <summary> https://tools.ietf.org/html/rfc5780#section-7.4 </summary> </member> <member name="T:STUN.Messages.StunAttributeValues.ReflectedFromStunAttributeValue"> <summary> https://tools.ietf.org/html/rfc3489#section-11.2.11 </summary> </member> <member name="T:STUN.Messages.StunAttributeValues.ResponseAddressStunAttributeValue"> <summary> https://tools.ietf.org/html/rfc3489#section-11.2.2
