This tutorial will walk you through the process of setting up Dynamic DNS on an EdgeRouter. In my network topology, the WAN is connected to eth2; change that to whatever interface you would like.

  1. Create an account with a supported service provider. If you do not want to use one of the below providers, I have written a different tutorial here. As of now, they are:
  2. Set the service provider, login, and password. Modify the service from dyndns to your service provider, and the username/password to match your credentials.

    edit service dns dynamic interface eth2 service dyndns
    set login $USERNAME
    set password $PASSWORD

  3. Set the hostname to update, modifying my domain for yours. You can also repeat this step for multiple host names.

    set host-name dlasley.net

  4. Commit and save

    commit
    save
