IP Address Distribution
The “IP Address Distribution” section of the Configure Broadband Connection (Coax) screen allows the user
to configure the TG590 Router’s Dynamic Host Configuration Protocol (DHCP) server parameters. The DHCP
automatically assigns IP addresses to network devices. If enabled, make sure to configure the network
devices as “DHCP Clients.” There are three options in this section:
Disabled,
DHCP Server, and
DHCP Relay.
Caution! We strongly recommend leaving this setting at “Disabled”.
Disabled
Select this option if statically assigning IP addresses to the network devices.
DHCP Server To set up the Broadband Connection (Coax) to function as a DHCP server:
1. Select DHCP Server.
2. Enter the IP address at which the TG590 Router starts issuing addresses in the “Start IP Address” text
boxes. Since the TG590 Router’s default IP address is 192.168.1.1, the Start IP Address must be 192.168.1.2.
3. Enter the end of the IP address range used to automatically issue IP addresses in the “End IP Address” text
boxes.
4. Enter the subnet mask address in the “Subnet Mask” text boxes. The subnet mask determines which
portion of a destination LAN IP address is the network portion, and which portion is the host portion.
5. If a Windows Internet Naming Service (WINS) is being used, enter the WINS server address in the “WINS
Server” text boxes.
6. Enter the amount of time a network device will be allowed to connect to the TG590 Router with its
currently issued dynamic IP address in the “Lease Time in Minutes” text box. Just before the time is up, the
device’s user will need to
make a request to extend the lease or get a new IP address.
7. Click in the “Provide Host Name If Not Specified by Client” check box to have the TG590 Router
automatically assign network devices with a host name, in case a host name is not provided by the user.
DHCP Relay Select this option to have the TG590 Router function as a DHCP relay, and enter the IP address in
the screen that appears.
