Configuring via Web-based Interface

When all needed settings are configured, click the

Save

button.

In the

Static DHCP

section, you can specify MAC address and IP address pairs (set a fixed IP

address in the local area network for a device with a certain MAC address). The router assigns IP

addresses in accordance with the specified pairs only when the DHCP server is enabled (in the

DHCP server

section, in the

Mode

drop-down list, the

Enable

value is selected).

Figure 73. The section for creating MAC-IP pairs.

To create a MAC-IP pair, click the

Add

button. In the

IP

field, enter an IP address which will be

assigned to the device from the LAN, then in the

MAC

field, enter the MAC address of this device.

In the

Host

field, specify a network name of the device for easier identification (

optional

).

Also you can create a MAC-IP pair for a device connected to the router's LAN at the moment. To do

this, select the relevant value from the

Known IP/MAC

addresses drop-down list (the

IP

and

MAC

fields will be filled in automatically).

When all needed MAC-IP pairs are specified, click the

Save

button.

Existing MAC-IP pairs are displayed in the table of the

Static DHCP

section. To remove a pair,

select the checkbox in the relevant line in the table and click the

Remove

button. Then click the

Save

button.
