This guide shows you how to configure your UniFi Gateway equipment UniFi to access your services and devices via Infomaniak DynDNS.

Prerequisites

• Have a UniFi Gateway device (e.g., UDM Pro/SE, UDR, UXG, Ultra or USG).
• A dynamic DNS must have been created on the relevant domain via the Infomaniak Manager.

DynDNS Configuration on UniFi Gateway

UniFi devices include a configurable DynDNS client via the UniFi Network interface:

1. Access your UniFi Network controller (via the local IP address or the UniFi cloud portal).
2. Go to Settings (gear icon).
3. In the left menu, select Internet.
4. Click on the relevant WAN interface (usually "WAN" or "Primary").
5. Scroll down to the Dynamic DNS section and click on Create New Dynamic DNS.
6. Fill in the fields with the following information:
   • Service: Select Custom.
   • Server: infomaniak.com
   • Hostname: The full domain name configured (e.g., my-domain.xyz or ddns.my-domain.xyz).
   • Username: The identifier defined in the Infomaniak Manager when creating the DynDNS.
   • Password: The password defined in the Infomaniak Manager.

   • Request URL (Update URL): Copy the URL below exactly (UniFi requires the use of %h for the domain and %i for the IP address):

     https://infomaniak.com/nic/update?hostname=%h&myip=%i

7. Click on Apply Changes (apply changes).

Note: The UniFi device will automatically replace the variables with your actual information when sending the request. Once saved, the status should display "Good" after one to two minutes.

Firewall and port redirection (NAT)

To access a specific service on your local network (NAS, camera, server) from the outside, you must create a redirection rule:

1. In Settings, go to Security > Port Forwarding.
2. Click on Create New Rule.
3. Configure the settings:
   • Name : A clear name (e.g., NAS Access).
   • Forward IP : The local IP address of your device (e.g., 192.168.1.123).
   • Forward Port : The port of the service in question.
   • Protocol : Select the required protocol (often TCP).
4. Save the rule.
