Chapter 5: Configuring the Gateway
The Setup Tab
Wireless-G ADSL Gateway
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. It is recommended that you 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.
•
DHCP Server. If you enable the DHCP Server or DHCP Relay for the Local DHCP server, enter the IP adresss
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 default, as shown in Figure 5-9, 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.
•
Time Setting. This is where you set the time zone for your Gateway.
