If you change the IP address and click Save Settings, the GUI will not respond. Open a new connection
to the new IP address and log in again. Be sure the LAN host (the machine used to manage the router)
has obtained IP address from newly assigned pool (or has a static IP address in the router's LAN
subnet) before accessing the router via changed IP address.

Subnet mask (factory default: 255.255.255.0).

In the DHCP section, select the DHCP mode:

None: the router's DHCP server is disabled for the LAN

DHCP Server. With this option the router assigns an IP address within the specified range
plus additional specified information to any LAN device that requests DHCP served
addresses.

DHCP Relay: With this option enabled, DHCP clients on the LAN can receive IP address
leases and corresponding information from a DHCP server on a different subnet. Specify
the Relay Gateway, and when LAN clients make a DHCP request it will be passed along to
the server accessible via the Relay Gateway IP address.

address pool. Any new DHCP client joining the LAN is assigned an IP address in this range.
The default starting address is 192.168.10.2. The default ending address is 192.168.10.100.
These addresses should be in the same IP address subnet as the router's LAN IP address.
You may wish to save part of the subnet range for devices with statically assigned IP
addresses in the LAN.

Primary and Secondary DNS servers: If configured domain name system (DNS) servers are
available on the LAN enter their IP addresses here.

network, the Windows NetBIOS server.
