If WAN Port Mode is set to "Bridge Mode", the following choices are displayed in place of the above choices,
because the device is functioning as a bridge in a network that contains another router.
Router IP Address
The IP address of the this device on the local area network. Assign any unused IP address in the range of IP
addresses available for the LAN. For example, 192.168.0.101.
Subnet Mask
The subnet mask of the local area network.
Gateway
The IP address of the router on the local area network. For example, 192.168.0.1.
Primary DNS Server, Secondary DNS Server
Enter the IP addresses of the DNS Servers. Leave the field for the secondary server empty if not used.
DHCP Server Settings
DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you configure the built-in
DHCP Server to assign IP addresses to the computers and other devices on your local area network (LAN).
Enable DHCP Server
Once your router is properly configured and this option is enabled, the DHCP Server will manage the IP
addresses and other network configuration information for computers and other devices connected to your
Local Area Network. There is no need for you to do this yourself.
The computers (and other devices) connected to your LAN also need to have their TCP/IP configuration set to
"DHCP" or "Obtain an IP address automatically".
When you set Enable DHCP Server, the following options are displayed.
DHCP IP Address Range
These two IP values (from and to) define a range of IP addresses that the DHCP Server uses when assigning
addresses to computers and devices on your Local Area Network. Any addresses that are outside of this
range are not managed by the DHCP Server; these could, therefore, be used for manually configured devices
or devices that cannot use DHCP to obtain network address details automatically.
It is possible for a computer or device that is manually configured to have an address that does reside within
this range. In this case the address should be reserved (see DHCP Reservation below), so that the DHCP
Server knows that this specific address can only be used by a specific computer or device.
Your router, by default, has a static IP address of 192.168.0.1. This means that addresses 192.168.0.2 to
192.168.0.254 can be made available for allocation by the DHCP Server.
Example:
Your router uses 192.168.0.1 for the IP address. You've assigned a computer that you want to designate as a
Web server with a static IP address of 192.168.0.3. You've assigned another computer that you want to
designate as an FTP server with a static IP address of 192.168.0.4. Therefore the starting IP address for your
DHCP IP address range needs to be 192.168.0.5 or greater.
Example:
Suppose you configure the DHCP Server to manage addresses From 192.168.0.100 To 192.168.0.199. This
means that 192.168.0.3 to 192.168.0.99 and 192.168.0.200 to 192.168.0.254 are NOT managed by the
DHCP Server. Computers or devices that use addresses from these ranges are to be manually configured.
Suppose you have a web server computer that has a manually configured address of 192.168.0.100. Because
this falls within the "managed range" be sure to create a reservation for this address and match it to the
relevant computer (see Static DHCP Client below).
