What is NAT?
NAT is an acronym for Network Address Translation. At any given time, there are many hundreds of devices on the Hastings College network accessing the Internet. Because we do not have hundreds of public IP addresses, all these devices must share. This process of translating from multiple on-campus addresses to the shared public address is called NAT. This is the same thing a home router does (on a smaller scale) to allow multiple devices to connect to a single home Internet connection.


How does this affect my Gaming System?

Most Gaming Systems recognizes three NAT statuses:

With an OPEN NAT type, you’re able to chat with other people, as well as join and host multiplayer games with people who have any NAT type on their network.

With a MODERATE NAT type, you’re able to chat and play multiplayer games with some people; however, you might not be able to hear or play with others, and normally you won’t be chosen as the host of a match.

With a STRICT NAT type, you’re only able to chat and play multiplayer games with people who have an OPEN NAT type. You can’t be chosen as the host of a match.

At Hastings College you will most likely see your Gaming System report a STRICT NAT.


What can be done to change the NAT type? Can you make it more open?
Unfortunately the NAT type cannot be changed or opened on campus. This is not due to a limitation placed by IT, but by limitations with the gaming systems itself. These gaming systems are designed for use in a home environment where it would be the only gaming system on that Internet connection. A more open NAT type depends on all incoming gaming system traffic on that connection to be sent to a single gaming console. With the large number of gaming consoles sharing the campus Internet connection, it is not possible to improve on Strict NAT


Can you turn on UPnP?
We cannot. UPnP is designed for consumer style home routers, and does not work in large enterprise networks like that of Hastings College.
