ADSL Gateway with 4-Port Switch
Optional Settings (Required by some ISPs)
•Host Name and Domain Name. These fields allow you to supply a host and domain name for the Gateway. Some ISPs require these names as identification. You may have to check with your ISP to see if your broadband Internet service has been configured with a host and domain name. In most cases, leaving these fields blank will work.
•MTU. The MTU (Maximum Transmission Unit) setting specifies the largest packet size permitted for network transmission. Select Manual and enter the value desired. You should leave this value in the 1200 to 1500 range. By default, MTU is configured automatically.
Network Setup
•Router IP. The values for the Gateway’s Local IP Address and Subnet Mask are shown here. In most cases, keeping the default values will work.
•Local IP Address. The default value is 192.168.1.1.
•Subnet Mask. The default value is 255.255.255.0.
•Network Address Server Settings (DHCP). A Dynamic Host Configuration Protocol (DHCP) server automatically assigns an IP address to each computer on your network for you. Unless you already have one, it is highly recommended that you leave the Gateway enabled as a DHCP server.
•Local DHCP Server. DHCP is already enabled by factory default. If you already have a DHCP server on your network, set the Gateway’s DHCP option to Disable. Only use DHCP Relay if requested by your ISP; your ISP will supply you with the IP Address
•DHCP Server. If you enable the DHCP Server or DHCP Relay for the Local DHCP server, enter the IP address for the DHCP server in the fields.
•Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. This value must be 192.168.1. 2 or greater, because the default IP address for the Gateway is 192.168.1.1.
•Number of Address. Enter the maximum number of computers that you want the DHCP server to assign IP addresses to. This number cannot be greater than 253. By defaul, the range is 192.168.1.100 to 192.168.1.149.
•DHCP Address Range. The range of DHCP addresses is displayed here.
•Client Lease Time. Enter the minutes in the field.
