Chapter 5 Using Network Connections
Internet Protocol
Select one of the following Internet Protocol options from the “Internet Protocol”
Obtain an IP Address Automatically This option is selected by default. Change only if required by the ISP. The server that assigns the Router with an IP address also assigns a subnet mask. Override the dynamically assigned subnet mask by selecting the “Override Subnet Mask” and entering a different subnet mask.
Use the Following IP Address Select this option to configure the Router to use a permanent (static) IP address. The ISP should provide this address.
DNS Server
The Domain Name System (DNS) is the method by which website or domain names are translated into IP addresses. The Router can be configured to auto- matically obtain a DNS server address, or the address can be entered manually, according to the information provided by the ISP.
To configure the connection to automatically obtain a DNS server address, select Obtain DNS Server Address Automatically from the “DNS Server”
Routing
Select Advanced or Basic from the “Routing”
Routing Mode Select one of the following Routing modes:
•Route - Select this option to cause the Router to act as a router between two networks.
•NAT - Select this option to activate Network Address Translation (NAT), which translates IP addresses to a valid, public address on the Internet. NAT adds security, since the IP addresses of the devices on the network are not transmitted over the Internet. In addition, NAT allows many addresses to exist behind a single valid address. Use the NAT routing mode only if the local network consists of a single device, or collisions may occur if more than one device attempts to communicate using the same port.
