The Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server assigns available IP addresses to each computer on your network automatically. If you choose to enable the DHCP server option, you must configure all of the PCs on your LAN to connect to a DHCP server.

If the Router's DHCP server function is disabled, you have to carefully configure the IP address, Mask, and DNS settings of every computer on your network. Be careful not to assign the same IP Address to different computers.

Make any changes to the available fields as described below.

Enable DHCP Server: Check the box to enable the DHCP Server. If you already have a DHCP server on your network, leave the box blank.

Dynamic IP
Client Lease Time: This is the lease time assigned if the computer (DHCP client) requests one. The range is 5 ~ 43,200 minutes.
Range Start/End: Enter a starting IP address and ending IP address to make a range to assign dynamic IPs. The default range is 100 ~ 149.

Static IP
The administrator can assign the Static IP for the specific client based on this user’s MAC address. Enter the Static IP Address and MAC Address, and then click the Add to list button. You can set up to 30 static IP entries.

DNS
You can assign the DNS server(s) to the DHCP clients. This is optional, and the Router will use these for quicker access to functioning DNS service.  

WINS Server
Windows Internet Naming Service (WINS) is a service that resolves NetBIOS names to IP addresses. The WINS is assigned if the computer (DHCP client) requests one. If you do not know the WINS, leave it as 0.

Click the Save Settings button to save the DHCP settings or click the Cancel Changes button to undo the changes.
