Maximum Number of DHCP Users 
Enter the maximum number of users to which the DHCP server 
can assign IP addresses for use in the LAN. This number cannot 
be greater than 254 minus the starting IP address described 
above. 
Client Lease Time 
The Client Lease Time is the amount of time an IP address is 
valid. IP address leases are renewed automatically by your PC 
and other devices that use DHCP to obtain IP addresses. If a lease 
is allowed to expire, the IP address will be returned to the pool of 
available IP addresses that can be assigned by the DHCP server 
as new devices are added to your network. The default is 60 
minutes when the gateway is online. 
LAN Static DNS (Domain Name Server) 1-3 
DNS is used by a PC or other client devices to discover the public 
IP address associated with a URL or the name-based address of a 
website. You can manually specify which DNS servers are to be 
used by devices in your network by entered the IP addresses of 
those servers in  these fields. Otherwise, the gateway will forward 
the DNCS server information from your service provider 
automatically. The default is to leave these fields blank.  
Time Zone 
Select the time zone for your location. If your location follows 
daylight saving time, select Automatically adjust clock for 
daylight saving time. 
 
Setup > DDNS 
Dynamic Domain Name Service (DDNS) provides the residential gateway (that may 
have a changing IP address) with a host name or URL resolvable by network 
applications through standard DNS queries. DDNS is useful when you are hosting 
your own website, FTP server, or other server behind the device. Before using this 
feature, you need to sign up for DDNS service. 
Select the DDNS tab to open the Setup DDNS page.
