12.2 DHCP reservation
12.2.1 Overview
Through the DHCP reservation function, specified clients can always obtain the same IP address
when connecting to the router, ensuring that the router's "Virtual server", "DDNS", "DMZ host"
and other functions can function normally. This function takes effect only when the DHCP server
function of the router is enabled.
To access the configuration page, log in to the web UI of the router, and choose System Settings >
DHCP Reservation.
Parameter description

12.2.2 Assign static IP addresses to LAN clients
Scenario: You have set up a FTP server within your LAN.
Goal: Assign a fixed IP address to the host of the FTP server and prevent the failure of access to the
FTP server owing to the change of IP address.
Solution: You can configure the DHCP reservation function to reach the goal.
Assume that the information of the FTP server includes:
− The fixed IP address for the server: 192.168.0.136
− MAC address of the FTP server host: D4:61:DA:1B:CD:89
