I noticed from the recent Warhawk BETA e-mail that many users weren't aware of their current NAT situation, or what it even meant.
- DMZ (Demilitarized Zone)
Short for demilitarized zone, a computer or small subnetwork that sits between a trusted internal network, such as a corporate private LAN, and an untrusted external network, such as the public Internet.
- MAC Address (Media Access Control Address)
Short for Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium. Consequently, each different type of network medium requires a different MAC layer.
- NAT (Network Address Translation)
Short for Network Address Translation, an Internet standard that enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT box located where the LAN meets the Internet makes all necessary IP address translations.
In TCP/IP and UDP networks, an endpoint to a logical connection. The port number identifies what type of port it is. For example, port 80 is used for HTTP traffic.
- Port Range Forward
An interface on a computer to which you can connect a device. Personal computers have various types of ports. Internally, there are several ports for connecting disk drives, display screens, and keyboards. Externally, personal computers have ports for connecting modems, printers, mice, and other peripheral devices.
- Static IP
Generally refers to elements of the Internet or computer programming that are fixed and not capable of action or change. The opposite of static is dynamic.
- TCP (Transmission Control Protocol)
Abbreviation of Transmission Control Protocol, and pronounced as separate letters. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.
- UDP (User Datagram Protocol)
Abbreviated UDP, a connectionless protocol that, like TCP, runs on top of IP networks. Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and receive datagrams over an IP network. It's used primarily for broadcasting messages over a network.
- UPnP (Universal Plug and Play)
Short for Universal Plug and Play, a networking architecture that provides compatibility among networking equipment, software and peripherals of the 400+ vendors that are part of the Universal Plug and Play Forum.
You'll be disconnected from the PSN while you perform your test. Once complete you'll know which NAT Type your PS3 is.
If your NAT Type 1 or 2 then you don't need to change a thing, everything is working as it should. If you're NAT Type 3 then you're in the right place and should try these steps. There is no guarantee what worked for me will work for you and since we all have different routers and I cannot offer support on your personal situation. The best I can do is tell you what worked for me and hope you can put the pieces together.
Congratulations your PS3 is now NAT Type 2 and fully functional!
