This section is common for all the Internet Connection Types. Some of these settings may be

required by your ISP. Verify with your ISP before making any changes.

Host Name

—Some ISPs, usually cable ISPs, require a host name as identification. You may

need to check with your ISP to see if your broadband Internet service is configured with a host

name. In most cases you can leave this field blank.

Domain Name

—Some ISPs, usually cable ISPs, require a domain name as identification. You

may need to check with your ISP to see if your broadband Internet service is configured with a

domain name. In most cases you can leave this field blank.

MTU

—MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for

Internet transmission. Select

Manual

if you want to manually enter the largest packet size that

is transmitted. To have the Router select the best MTU for your Internet connection, keep the

default setting,

Auto

DDNS

The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a

fixed host and domain name to a dynamic Internet IP address. It is useful when you are hosting

your own website, FTP server, or other server behind the Router.

Before you can use this feature, you need to sign up for DDNS service at DynDNS.org or

TZO.com.

DDNS Service. If your DDNS service is provided by DynDNS.org, then select

DynDNS.org

from

the drop-down menu. If your DDNS service is provided by TZO.com, then select

TZO.com

from

the drop-down menu.To disable DDNS Service, select

IP Reserved for Internal Usage—

Enter the reserved IP between 1 and 254.

Server Settings (DHCP)

The Router can be used as your network’s DHCP (Dynamic Host Configuration Protocol) server,

which automatically assigns an IP address to each PC on your network. Unless you already have

one, it is highly recommended that you leave the Router enabled as a DHCP server.

DHCP Server

—DHCP is enabled by default. If you already have a DHCP server on your network,

or you don't want a DHCP server, then select

Disabled

(no other DHCP features will be

available). If you already have a DHCP server on your network, and you want the Router to act

as a Relay for that DHCP Server, select

DHCP Relay

, then enter the DHCP Server IP Address.

Starting IP Address

—Enter a value for the DHCP server to start with when issuing IP

addresses. This value will automatically follow your local IP address settings. Normally, you

assign the first IP address for the Router (e.g. 192.168.1.1) so that you can assign an IP address to

other devices starting from the 2nd IP address (e.g. 192.168.1.2). The last address in the subnet

is for subnet broadcast (e.g. 192.168.1.255) so that the address cannot be assigned to any host.

Maximum Number of DHCP Users

—Enter the maximum number of PCs that you want the

DHCP server to assign IP addresses to. This number cannot be greater than the available host

addresses in the subnet (e.g. 253 for /24 subnet). In order to determine the DHCP IP Address

range, add the starting IP address (e.g., 100) to the number of DHCP users.

Client Lease Time

—The amount of time a DHCP client can keep the assigned IP address before

it sends a renewal request to the DHCP server. The default value is 0, which actually means one

day.

Static DNS 1-3

—If applicable, enter the IP address(es) of your DNS server(s).

WINS

—The Windows Internet Naming Service (WINS) performs name resolution function

(similar to DNS) in the Windows network environment. It can help you to determine the IP

address of a remote Windows PC from its computer name. If you have a WINS server, enter that

server's IP Address here. Otherwise, leave this blank.

IPv6

IPv6 Address

—If you selected

dual-stack

option under IP Versions Setup screen, enter the

IPv6 address on the LAN side of the Router.

Prefix Length

—Enter the IPv6 prefix length. The default is 64, which should not need to be

changed.

Router Advertisement

—Enabling this option allows the Router to send out IPv6 Router

Advertisement packets periodically. This helps IPv6 hosts to learn their IPv6 prefix and setup

their IPv6 Address automatically.

DHCPv6

To enable the DHCP v6 feature, select

Enable

. To disable DHCP v6, select

Disable

.

Lease time—

Enter the lease time in minutes.

DHCP address range start—

Enter the starting DHCP v6 IP address.
