# Step 10. Specify Connection Ports

At the **Port Configuration** step of the wizard, specify connection settings for Veeam ONE Web Client:

- In the **Website port** field, type a number of the port that will be used to access the Veeam ONE Web Client through a web browser.

  The default port number is `1239`.

- In the **Certificate** list, choose a certificate that will be used to secure traffic between the Veeam ONE Web Client and a web browser.

  You can choose an existing certificate installed on the machine or select the setup wizard to generate a self-signed certificate.

  ::: note

  - If you generate or choose a self-signed certificate, you must configure a trusted connection between the Veeam ONE Web Client and a web browser later. For details, see [Accessing Veeam ONE Components](access.md#configure_trusted).
  - You can change the selected certificate after installation. For details, see [Change Default Certificate](upgrade_change_certificate.md).
