How to configure the DHCP server of the Lock

Modified on Tue, 05 Apr 2022 at 08:41 AM

The DHCP server is automatically enabled by default (from Lock SW 2.3.2). Do not switch off the DHCP server if there is no other DHCP server in the Lock’s LAN network. You can configure the Lock’s DHCP server at Network > LAN DHCP server. You should always use the default settings if possible.

General Setup

  • Disable DHCP server: disable the Lock’s DHCP server. Do not disable the DHCP server if there is no other DHCP server in the Lock’s LAN network.
  • Start: start giving IP addresses after this many addresses starting from the beginning of the IP address space. You can use this option to have free addresses at the beginning of the IP address space for fixed IP addresses. (Default: 10)
  • Limit: maximum number of available DHCP IP addresses. (Default: 50)
  • Leasetime: keep an IP address reserved for a specific network device for this time. Note! The Lock does not remember these addresses after rebooting the Lock. (Default: 12h)

Active Leases This sections shows the IP addresses that the Lock has already given to network devices.
Static Leases At this section you can set the Lock’s DHCP server to always give a specific IP address to a specific network device.

  1. Click the “Add” button. A new row will be created.
  2. If the network device has already got an IP address from the Lock’s DHCP server, it’s MAC- and IP-address are already available in the dropdown menus. You can use these or set your own by selecting “custom”. On the hostname field you can copy the network device’s hostname from the “Active Leases” section above, enter your own or just leave the field blank.
  3. Finally click the “Save” button to save the changes.

If you want to remove a static lease, click the Delete button at the specific row and finally the “Save” button.

Advanced Settings

  • Dynamic DHCP: If checked, only clients listed on Static Leases will be served. Other clients will not get an IP address from Lock
