NAT (Network Address Translation)

NAT is a function allows several networked PCs to share an Internet account using only a single IP address, which may be statically or dynamically assigned by your Service Provider. Click “Add” to add more rule to NAT Configuration.

The WMG accomplishes this address sharing by translating the internal LAN IP addresses to public unique address/addresses on the Internet. The internal LAN IP addresses can be either private addresses or registered addresses. In NAT type, you can choose Many-to-one or Many-to-many. In Many-to-one configuration, it translates multiple LAN IP addresses to one single public address on Internet. In Many-to-many configuration, it translates multiple LAN IP addresses to a range of public addresses. This will be used when your service provider provide you a range of IP addresses.

DMZ

A DMZ (Demilitarized Zone) is a buffer zone between the Internet, and your private networks. It can be a public network typically used for Web, FTP and E-Mail servers that are accessed by external clients on the Internet. Separating these public access server with your private network provide higher security for your network.

A DMZ Host is a computer that has all external Internet traffic forwarded to it. This allows a computer to be exposed to unrestricted two-way communication. This feature should be used only when necessary, since it is not protected by any security rules of the firewall.
