Wireless-N Gigabit Security Router with VPN
LAN
The LAN Setup section allows you to change the Router’s local network settings for the four Ethernet ports.
IPv4
The Router’s Local IPv4 Address and Subnet Mask are shown here. In most cases, you can keep the defaults.
Local IP Address. Enter the IPv4 address on the LAN side. The default value is 192.168.1.1.
Subnet Mask. Select the subnet mask from the drop-down menu. The default value is 255.255.255.0.
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. This is 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).
