server.
DNS Relay
When DNS Relay is enabled, the router plays the role of a DNS server. DNS requests sent to the
router are forwarded to the ISP's DNS server. This provides a constant DNS address that LAN
computers can use, even when the router obtains a different DNS server address from the ISP
upon re-establishing the WAN connection. You should disable DNS relay if you implement a
LAN-side DNS server as a virtual server.
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.
