the router can be used as a dhcp (dynamic host configuration protocol) server on your network. a dhcp server automatically assigns available ip addresses to computers on your network. if you choose to enable the dhcp server option, all of the pcs on your lan must be set to obtain an ip address automatically from a dhcp server.
(by default, windows computers are set to obtain an ip automatically.)
if the router's dhcp server function is disabled, you have to carefully configure the ip address, subnet mask, and dns settings of every computer on your network. be careful not to assign the same ip address to different computers.
you can also set up to 30 static ip entries on this screen.
enable dhcp server. check the box to enable the dhcp server. if you already have a dhcp server on your network, leave the box unchecked.
dynamic ip
client lease time. the client lease time is the amount of time a network user will be allowed connection to the router with their current dynamic ip address. enter the amount of time, in minutes, that the user will be “leased” this dynamic ip address. the range is 5-43,200 minutes.
range start/end. enter a starting ip address and ending ip address to create a range of available ip addresses.
the default range is 100~149. enter a value for the dhcp server to start with when issuing ip addresses. this value must be 192.168.1. 2 or greater, because the default ip address for the router is 192.168.1.1.
static ip
static ip address. if necessary, you can assign a static ip address to a specific computer based on its mac address. complete the static ip address field.
mac address. enter the mac address of the specific computer to which you will assign a static ip address.
to add a static ip entry, click the add to list button. to delete a static ip entry, select the listed entry, and click the delete selected entry button.
dns
you can assign dns server(s) to the dhcp clients so the router will use the dns server(s) for faster access to functioning dns server(s). you do not need to complete either of these dns server fields; it is an optional feature.
wins
windows internet naming service (wins) is a service that resolves netbios names to ip addresses. wins is assigned if the computer (dhcp client) requests one. if you do not know the ip address of the wins server, keep the default, 0.0.0.0.
