This guide explains how to access a Swisscom Internet Box connected to the Internet with a dynamic IP via a domain name.

Prerequisites

• Have a Box that allows you to configure a custom dynamic DNS provider.
• A dynamic DNS must have been created on the relevant domain.

Link Swisscom Internet Box to a domain name

To do this:

1. Log in to the Swisscom Box administration interface (http://192.168.1.1 for example).
2. Enable the expert view (toggle button at the bottom left).
3. Click on Network.
4. Click on the DynDNS tab.
5. Check the box to Enable DynDNS.
6. Select the provider Infomaniak from the dropdown menu.
7. Fill in the following fields:
   • Hostname: the URL configured in the Manager when adding the Dynamic DNS
   • Username : the identifier set in the Manager when adding the Dynamic DNS
   • Password : the password set in the Manager when adding the Dynamic DNS

If the box indicates that port redirection is not possible because you do not have a public IP address, contact Swisscom to have them disable the CGnat. Refer to this guide for more information.
