In the restricted cone NAT, all requests from an internal IP address and port are mapped to a fixed external IP address and port. ("carrier nat"). NAT1： Full Cone NAT (完全圆锥型) 2. Open NAT/Cone NAT/Endpoint-Independent mapping and filtering behavior means that the mapped ports are being "opened", either permanently, if you use Static NAT/Port Forwarding, or "opened", for the duration of each session until the timer reach 0, if Full cone NAT Also known as one to one NAT. Once an internal address (iAddr:iPort) is mapped to an external address (eAddr:ePort), any packets from iAddr:iPort are sent through eAddr:ePort.

(I don't know if this was ever fixed in a firmware update or not) and if yes, is Full-cone NAT really that important and how will it affect me? thanks! Great answer! Essentially, what we call a "Static NAT" is simply a single mapping between a host address and NAT address, and any number of connections (5-tuples) can be pushed through that single mapping -- hence, it is not a symmetric relationship between mappings and connections. There are three NAT options on Xbox One, and they are Open, Moderate and Strict.
