MAC Address

NAT

Network Address Translation. This process allows all of the computers on your home network to use one IP address. The NAT capability of the Device, allows you to access the Internet from any computer on your home network without having to purchase more IP addresses from your ISP.

Network Address Translation can be used to give multiple users access to the Internet with a single user account, or to map the local address for an IP server(such as Web or FTP) to a public address. This secures your network from direct attack by hackers, and provides more flexible management by allowing you to change internal IP addresses without affecting outside access to your network. NAT must be enabled to provide multi-user access to the Internet or to use the Virtual Server function.
