DHCP connection, and “Manual,” which allows the MTU to be set manually.
Internet Protocol
This section includes three options: No IP Address, Obtain an IP Address Automatically, and Use the
Following IP Address.
No IP Address Select this option if the connection has no IP address. This is useful if the connection is
operating under a bridge.
Obtain an IP Address Automatically Select this option if the ISP requires the connection to obtain an IP
address automatically. The server assigning the IP address also assigns a subnet mask address, which can be
overridden by clicking in the “Override Subnet Mask” check box and entering another subnet mask address.
Additionally, the DHCP lease can be renewed and/or released by clicking on the appropriate “DHCP Lease”
button. The “Expires In” value displays how long until the DHCP lease expires.
Use the Following IP Address Select this option if the connection uses a permanent (static) IP address. The ISP
should provide this address, along with a subnet mask address, default gateway address, and, optionally,
primary and secondary DNS server addresses.
DNS Server
The Domain Name System (DNS) is the method by which website or domain names are translated into IP
addresses. This connection can be configured to automatically obtain a DNS server address, or an address can
be specified 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” drop-down list. To manually configure DNS server addresses, select Use
the Following DNS Server Addresses. Specify up to two different DNS server addresses, one primary, the
other secondary.
IP Address Distribution
The “IP Address Distribution” section of the Configure Broadband Connection (Ethernet) screen is used to
configure the TG590 Router’s Dynamic Host Configuration Protocol (DHCP) server parameters. 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.
