Chapter 10 WAN WAN IP Address The WAN IP address is an IP address for the NBG2105, which makes it accessible from an outside network. It is used by the NBG2105 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG2105 tries to access the Internet. If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP encapsulation method). DNS Server Address Assignment Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The NBG2105 can get the DNS server addresses in the following ways. 1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields. 2 If your ISP dynamically assigns the DNS server IP addresses (along with the NBG2105's WAN IP address), set the DNS server fields to get the DNS server address from the ISP. WAN MAC Address The WAN port's MAC address can be configured by either using the factory default or cloning the MAC address from a computer on your LAN. Choose Clear Mac Clone to select the factory assigned default MAC Address. Otherwise, press the Clone MAC address button on the side of the NBG2105 to clone the MAC address of the computer connected to the NBG2105. Once it is successfully configured, the address will be copied to configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN Port. 10.4 WAN Interface Setup Click Network > WAN to change how your NBG2105's WAN interface accesses your ISP. The screen differs according to the WAN Access Type you choose. 10.4.1 Static IP Select Static IP from WAN Access Type to configure all NBG2105 WAN IP configuration settings manually. 74 NBG2105 User's Guide
