DHCP Server To set up the TG590 Router 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 or higher.
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.
Additionally, to add a new product or product family, click New IP Range in the “Vendor Class ID” column
below “IP Address Distribution According to DHCP Option 60 (Vendor Class Identifier).” This generates the
“DHCP Server Pool Settings” screen. Set the device name, IP range, and priority level in the appropriate text
boxes, then click Apply.
DHCP Relay Select this option to have the TG590 Router function as a DHCP relay. To enter a new IP address
for the relay, click New IP Address. The “DHCP Relay Server Address” screen appears. Enter the new IP
address in the appropriate text boxes, then click Apply.
Routing
The TG590 Router can be configured to use static or dynamic routing. Dynamic
routing automatically adjusts how packets travel on the network, while static
routing specifies a fixed routing path to neighboring destinations.
There are two options in the “Routing” section of the “Configure Broadband
Connection (Ethernet)” screen: Basic or Advanced.
