DynDNS on LANCOM: step-by-step setup
LANCOM routers ship with a freely configurable DynDNS client via the LCOS Action Table that can call any DynDNS2 URL. With DNS Beacon your site stays reachable under a permanent hostname even when your WAN IP changes. Here's how to set it up.
Step by step
- Open the admin interface of your LANCOM and go to Communication → General → Action Table (LANconfig).
- Enter the values below. Your username is your account email, your password is an API key from the dashboard.
- Save the settings. Your hostname now updates automatically whenever your IP changes — usually within a minute.
Settings to enter
Communication → General → Action Table (LANconfig)
- Action (URL):
- https://api.dnsbeacon.com/nic/update?hostname=%h&myip=%a
- Hostname:
- myhouse.dnsfollowme.uk
- Username:
- your email address
- Password:
- your API key
In LANconfig, under Communication → General → Action Table, create a new action triggered on "Established" / IP change. LANCOM substitutes %h with the hostname and %a with the current IPv4 (use %z for IPv6). Embed your credentials as `https://<username>:<API key>@…` in the URL.
Need a free hostname first?
Create a free DNS Beacon account, add a hostname and generate an API key — then come back and finish the setup above.
