User's Manual

Subnet Mask: This is used to define the device IP classification for the chosen IP address

range. 255.255.255.0 is a typical netmask value for Class C networks which support IP

address range from 192.0.0.x to 223.255.255.x. Class C network netmask uses 24 bits to

identify the network and 8 bits to identify the host.

DHCP: You can disable or enable this function here.

DHCP Client Range: the range of IP addresses that will be assigned to each computer

connected with the router.

DHCP Lease Time: the IP addresses given out by the DHCP server will only be valid for

the duration specified by the lease time. Increasing the time ensure client operation without

interrupt, but could introduce potential conflicts. Lowering the lease time will avoid potential

address conflicts, but might cause more slight interruptions to the client while it will acquire

new IP addresses from the DHCP server. The time is expressed in seconds.

Static DHCP: click the Set Static DHCP button to go to the Static DHCP setup interface.

Domain name: this represents the name of your IP address.

802.1d Spanning Tree: Multiple interconnected bridges create larger networks using the

IEEE 802.1d Spanning Tree Protocol (STP), which is used for finding the shortest path

within the network and to eliminate loops from the topology. If the STP is turned on, the

router will communicate with other network devices by sending and receiving Bridge

Protocol Data Units (BPDU). STP should be turned off (selected by default) when this

router is the only bridge on the LAN or when there are no loops in the topology as there is

no sense for the bridge to participate in the Spanning Tree Protocol in this case.

It will come out the Static DHCP Setup interface after you click the Set Static DHCP

button.

Check the box to enable static DHCP, it allows you to reserve IP addresses and assign the

same IP address to the network device with the specified MAC address any time it requests

an IP address.

Note: If this IP address changed, you can log into the WEB configuration interface only using the new

IP address. AND if the new IP address and the original IP address are not in the same segment, the

Virtual Server and DMZ Host service will not work. If you need to enable these functions, you will have

to reset this IP address.
