DHCP Server

This guide explains how to configure a DHCP server for multiple LAN interfaces, enabling automatic IP address assignment to devices connected to the same network. It includes easy-to-follow steps to set up and test the configuration.

Overview​

A DHCP server automatically assigns IP addresses to devices in a network, simplifying network management. By configuring a DHCP server on the LAN interface, client devices can automatically connect to the network without manually setting IP addresses.

Enable DHCP and Configure Range

In the DHCP settings section, the DHCP server settings can now be configured as follows:

  • Enable DHCP: Check the DHCP Server option.

  • Set IP Range:

    • Enter the Start Range (e.g., 172.10.2.51 ).
    • Enter the End Range (e.g., 172.10.2.101).

  • Click on the Update button.

Client PC Configuration​

  • To ensure the DHCP server is working as expected:
    • Connect client PCs to the configured LAN ports.
    • Verify that:
      • The client receives an IP address within the configured DHCP range (e.g., 172.10.2.51 to 172.10.2.101).
      • Internet connectivity and Default Gateway (CGW) settings are functional.
    • Use the ipconfig or ifconfig command on the client PC to view the assigned IP address and gateway.
