Address restricted Nat

I was wondering the same thing myself - did the Multiplayer Test when it ran to completion I also did the Pull and hold both triggers and both bumpers at the same time and saw "Cone NAT" as well, the first page shows "Open" nat as well.

MS needs to post a better message in that test as in the following for "Different Types" of Cone NAT's in order to steer people to a possible solution.

Full Cone: A full 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. Furthermore, any external host can send a

packet to the internal host, by sending a packet to the mapped

external address.

Restricted Cone: 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.

Port Restricted Cone: 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.

Symmetric: 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.

Full cone NAT: Not very restrictive. all ports (incoming and outgoing) are able to reach to the device without being restricted

IP restrictive NAT : Has restrictions on incoming IPs but allows ports

Port restrictive NAT: Has restrictions on ports and incoming IPs

Symmetric NAT: very restrictive, new mapping for every different connection.

I have the same problem, I get open Nat and I get the message your Network is behind address restricted Nat. I don't have a problem playing online but I can't talk in party chat

It comes down to each ip only having 1 nat port . You cannot run multiple machines behind the same ip and have open nat on multiple machines . you will need to run a multi port switch with multiple ip address from your isp to have open nat on
every machine . You can have a open nat and restricted nats and blocked nats all running at the same time .behind one ip address . it comes down to direct play inside direct x basically xbox live can only have direct play open once per each Ip address .
