(The first IP address assigned by the  Router will be  randomly selected within the range you specify.)Because  the  Router’s  default  IP  address  is  192.168.1.1, the  Start  IP  Address must  be  192.168.1.2  or  greater, but smaller than 192.168.1.254. The default Start IP Address is 192.168.1.100.Maximum  Number  of  Users  Enter  the  maximum number of computers that you want the DHCP server to assign  IP  addresses  to.  This  number  cannot  be  greater than 253. The default is 50.IP Address Range  The range of available IP addresses is displayed.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. After the time is up, the user will be automatically assigned a new dynamic IP  address, or the lease will be renewed. The default is 0 minutes, which means one day.Static DNS  1-3 The Domain  Name  System (DNS)  is  how the  Internet  translates  domain  or  website  names  into Internet addresses or URLs. Your ISP will provide you with at least one DNS server IP address. If, however, you wish to use a different DNS server, enter its IP address (you can enter up to three DNS server IP addresses). These static DNS server(s) will  have  higher  priority  than  the  ISP’s  DNS  servers.  The Router will assign these DNS servers to the computers and other devices in your local network.WINS  The  Windows  Internet  Naming  Service  (WINS) manages each computer’s interaction with the Internet. If you use a WINS server, enter that server’s IP address here. Otherwise, leave this blank.Time SettingsTime SettingTime Zone  Select the time zone in which your network functions from this drop-down menu.Automatically  adjust  clock  for  daylight  saving changes  Select  this  option  to  have  the  Router automatically adjust for daylight saving time.RebootRebootReboot  Click Reboot to restart the Router.Click Save Settings to apply your changes, or click Cancel Changes to clear your changes.Setup > DDNSThe Router offers a Dynamic Domain Name System (DDNS) feature.  DDNS  lets  you  assign  a  fixed  host  and  domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, File Transfer Protocol (FTP) server, or other server behind the Router. Before  you  can  use  this  option,  you  need  to  sign up  for  DDNS  service  with  a  DDNS  service  provider,  www.dyndns.org or www.tzo.com.
