When all needed settings are configured, click the Apply 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).
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 Apply 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
Apply button.
Select the checkbox so that the devices connected to the router
obtain the address of the router as the DNS server address.
Deselect the checkbox so that the devices connected to the router
obtain the address transmitted by the ISP or specified on the
Advanced / DNS page as the DNS server address.
The start IP address of the address pool used by the DHCP server to
distribute IP addresses to clients.
The end IP address of the address pool used by the DHCP server to

of this period the leased IP address is revoked and can be distributed

addresses to the router's clients.
