manually configured. Suppose you have a web server computer

that has a manually configured address of 192.168.1.100.

Because this falls within the "managed range" be sure to create a

reservation for this address and match it to the relevant computer

(see Static DHCP Client below).

DHCP Lease Time

The amount of time that a computer may have an IP address

before it is required to renew the lease. The lease functions just as

a lease on an apartment would. The initial lease designates the

amount of time before the lease expires. If the tenant wishes to

retain the address when the lease is expired then a new lease is

established. If the lease expires and the address is no longer

needed than another tenant may use the address.

Always Broadcast

If all the computers on the LAN successfully obtain their IP

addresses from the Access Point's DHCP server as expected, this

option can remain disabled. However, if one of the computers on

the LAN fails to obtain an IP address from the Access Point's DHCP

server, it may have an old DHCP client that incorrectly turns off the

broadcast flag of DHCP packets. Enabling this option will cause the

Access Point to always broadcast its responses to all clients,

thereby working around the problem, at the cost of increased

broadcast traffic on the LAN.

Number of Dynamic DHCP Clients

In this section you can see what LAN devices are currently leasing

IP addresses.

Revoke: The Revoke option is available for the situation in which

the lease table becomes full or nearly full, you need to recover

space in the table for new entries, and you know that some of the

currently allocated leases are no longer needed. Clicking Revoke

cancels the lease for a specific LAN device and frees an entry in the

lease table. Do this only if the device no longer needs the leased IP

address, because, for example, it has been removed from the

network.

Add/Edit DHCP Reservation

This option lets you 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. This is almost the same as when a

device has a static IP address except that the device must still

request an IP address from the Access Point. The Access Point will

provide the device the same IP address every time. DHCP
