 Subnet Mask: Enter the router’s Subnet Mask, the default value is 255.255.255.0.
 Enable IGMP Snooping: If you select the option, please choose the IGMP Mode: Standard
Mode or Blocking Mode.
 DHCP Server: These settings allow you to configure the router‘s Dynamic Host Configuration
Protocol (DHCP) server function. The DHCP server is enabled by default for the router’s
Ethernet LAN interface. DHCP service will supply IP settings to computers which are
configured to automatically obtain IP settings that are connected to the router though the
Ethernet port. When the router is set for DHCP, it becomes the default gateway for DHCP
client connected to it. Keep in mind that if you change the IP address of the router, you must
change the range of IP addresses in the pool used for DHCP on the LAN.
 Start IP Address: Enter a value for the DHCP server to start with when issuing IP
addresses. Because the default IP address for the router is 192.168.1.1, the default Start
IP Address is 192.168.1.2, and the Start IP Address must be 192.168.1.2 or greater, but
smaller than 192.168.1.254.
 End IP Address: Enter a value for the DHCP server to end with when issuing IP
addresses. The End IP Address must be smaller than 192.168.1.254. The default End IP
Address is 192.168.1.254.
 Leased Time (hour): The Leased Time is the amount of time in which a network user will
be allowed connection to the router with their current dynamic IP address. Enter the
amount of time, in hours, then the user will be “leased” this dynamic IP address. After the
dynamic IP address has expired, the user will be automatically assigned a new dynamic IP
address. The default is 24 hours.
 Static IP Lease List: The function allows you to specify a reserved IP address for a PC on the
LAN, that PC will always obtain the assigned IP address each time when it accesses the
DHCP server. Reserved IP addresses should be assigned to servers that require permanent
IP settings. Click the Add Entries button in Figure 4-21, and then you will set the rule in the
screen as below.
Figure 4-22
 MAC Address: The MAC address of the computer on the LAN which you want to reserve
an IP.
 IP Address: The IP address you want to reserved to the computer.

second IP Address and Subnet Mask for LAN Interface through which you can also access to
the Web-based Utility as the default IP Address and Subnet Mask.
