If an Internet connection with a dynamic IPv4 address is used, the new IP address would have to be announced in a cumbersome way whenever the IP address changes. To bypass this issue the current IP address can be sent to a DynDNS service and a connection to the router can be established via a DNS name. The LANCOM Management Cloud features an integrated DynDNS service. Therefore the administration of the router as well as the DynDNS service are under one roof.

This article describes the configuration steps for the DynDNS service in the LANCOM Management Cloud.


  • LCOS as of version 10.42 on the LANCOM router (download latest version)
  • Access to the LMC including your own project 
  • The LANCOM router has to be connected to the LMC including a valid LMC license 
  • Configured Site with assigned Network and router
  • The Function Gateway has to be assigned to the router
  • Configured and functional Internet connection with public IPv4 address on the router
    • The Internet connection can be configured as follows: 
      • manually on the router via LANconfig / WEBconfig
      • manually via the detail configuration in the LMC
      • automatically via LMC addins
  • Web browser for accessing the LMC


1) Connect to the LMC, click on Sites and select the used site. 

2) Go to the tab WAN connections, select the option Use site based settings in the dropdown menu and click Create WAN connection.

3) Click on the Connections box at Name of WAN connection on device to display the configured Internet connections. Afterwards select the used Internet connection (in this example the connection INTERNET-DEFAULT). 

As an alternative you can also enter the name of the Internet connection manually.

4) Activate the option Use Dynamic DNS, adjust the Dynamic DNS subdomain if needed and click Save.

5) Go to the menu Devices, select the router which is assigned to the used site and click on the "dots" icon to gain access to the extended menu. 

6) Click on Configuration roll out to transfer the configuration changes to the devices.

7) Acknowledge the query by clicking Roll out.

8) The configuration of the DynDNS service for a site is now complete.

The current IP address can be read out in the menu Sites in the respective Site under WAN connections.
