•

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.

¾

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, and then you will set the rule in the screen as

below.

screen below (shown in Figure 4-25).

Virtual servers can be used for setting up public services on your LAN, such as DNS, Email and

FTP. A virtual server is defined as a service port, and all requests from the Internet to this service

port will be redirected to the computer specified by the server IP. Any PC that was used for a

virtual server must have a static or reserved IP Address because its IP Address may change when

using the DHCP function.

Some applications require that specific ports in the Router's firewall should be opened for access

by remote devices. Port Trigger dynamically opens up the 'Open Ports' in the firewall when an

application on the LAN initiates a TCP/UDP connection to a remote device using the triggering

ports. The Router allows the remote party from the WAN side to establish new connections back to

the application on the LAN side using the open ports. A maximum 32 entries can be configured.
