Change the DNS Forwarder DoT port

Suggest Edits

You can use outbound TCP port 443 or 853 forDoT connections. By default, the DoT port is 443. Complete this procedure to change the port.

📘

For this port, DNS Forwarder uses the hostname *.akaetp.net with dot as the ALPN. Make sure that your firewall allows these hostnames and the port you configure. You should also make sure that your organization has no proxy or SSL interception configuration in place that will break this connection.

To change the DNS Forwarder DoT port:

  1. In the Security Connector main menu, press 6 or use the arrow keys to select Manage DNS Forwarder and press Enter.

  2. In the menu that appears, press 5 or if necessary, use the arrow keys to select Modify DoT port and press Enter.

  3. Press C to continue and edit the port.

  4. Enter yes and press Enter. The VM reboots in 10 seconds following this change. After the reboot is complete, you can log in to the Security Connector console.
