a second DHCP server into the network, you will experience network errors and the network will

not function correctly.

;

Start IP: The Start IP Address indicates the beginning of the range at which the DHCP server

starts issuing IP addresses.

This value must be greater than the Routers IP address value. If the Routers IP address is

192.168.1.1 (The default) than the starting IP address must be 192.168.1. 2 or higher.

Note: If you change the start or end values, make sure the values are still within the same

subnet as the gateways IP address. In other words, if the gateways IP address is 192.168.1.1

(default) and you change the DHCP start/end IP addresses to be 192.128.1.2/192.128.1.100,

you will not be able to communicate to the gateway if your PC has DHCP enabled.

;

End IP: The End IP Address indicates the end of the IP address range.

The ending address must not exceed a Subnet Limit of 253; hence the maximum value that

can be entered in this example is 192.168.1.254.

If the DHCP server runs out of DHCP addresses, users will not get access to network

resources. If this happens you can increase the Ending IP address (to the limit of 255) or

reduce the lease time.

Note: If you change the start or end values, make sure the values are still within the same

subnet as the gateways IP address. In other words, if the gateways IP address is 192.168.1.1

(default) and you change the DHCP start/end IP addresses to be 192.128.1.2/192.128.1.100,

you will not be able to communicate to the gateway if your PC has DHCP enabled.

;

Lease Time: Lease Time is the amount of time a network user will be allowed connection to

the ARM-104_v3 ADSL2/2+ Router with their current Dynamic IP address. The amount of

time is in units of minutes; the default value is 3600 minutes (60 hours).

„

Enable DHCP Relay: Click the radio button to enable the DHCP Relay. When the gateway is

configured as DHCP server, it assigns the IP addresses to the LAN clients. When the gateway is

configured as DHCP relay, it is responsible for forwarding the requests and responses negotiating

between the DHCP clients and the server.

;

Relay IP: This is the IP Address given by the ISP.

„

Server and Relay Off: Click the radio button to enable. By turning off the DHCP server and relay

the network administrator must carefully configure the IP address, Subnet Mask and DNS settings

of every computer on your network. Do not assign the same IP address to more than one

computer and your Gateway must be on the same subnet as all the other computers.
