Open.NATNAT 遍历库
Open.NAT 是为 .NET 和 Mono 设计的 NAT 遍历库。Open.NAT 是 NAT 设备端口转发的类库，支持即插即用（UPNP）和端口映射协议（PMP）。
如果你正在开发类似媒体服务器，文件存储服务器，即时信息服务器等，你必须知道 NAT 遍历和计算机与外部设备连接的技术。
要做好这些，你必须熟悉 SSDP，UPNP 或者 PMP 协议，而且不同设备有很多的不同，需要不断测试。而 Open.NAT 正是提供了这些便利，它非常轻量级，而且提供 NAT 设备端口的转发，支持 UPNP 和 PMP 协议，使用 C# 编写，可以为 .NET 和 Mono 服务。
