DHCP Reservation

If you want a computer or device to always have the same IP address assigned, you can create a DHCP reservation. The router will assign the IP

address only to that computer or device.

Note:

This IP address must be within the DHCP IP Address Range.

Check this box to enable the reservation.

Enter the computer name or select from the drop-down menu and click

<<

.

Enter the IP address you want to assign to the computer or device. This IP Address must

be within the DHCP IP Address Range.

Enter the MAC address of the computer or device.

If you want to assign an IP address to the computer you are currently on, click this button

to populate the fields.

Click

Save

to save your entry. You must click

Save Settings

at the top to activate your

reservations.

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

Click

Revoke

to cancel the lease for a specific LAN device and free 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.

Note:

The Revoke option will not disconnect a PC with a current network session from the network; you would need to use MAC Address Filter to do that. Revoke will

only free up a DHCP Address for the very next requester. If the previous owner is still available, those two devices may both receive an IP Address Conflict error, or the

second device may still not receive an IP Address; in that case, you may still need to extend the “DHCP IP Address Range” to address the issue, it is located in the DHCP

Server section.

The Reserve option converts this dynamic IP allocation into a DHCP Reservation and adds the corresponding entry to the DHCP Reservations List.
