This guide explains how to manually update the server certificate on your On-Premise (BYOS) VPN Gateway. On an integrated cloud VPN server, the certificate updation process is automated and there is no need for user intervention.
On your On-Premise Access Gateway, you need to perform this manual update once every two years before the certificate expires. You will be notified by email when the certificate renewal is due so that you can update it on your server accordingly.
This update can be done using the wrapper tool 'utnservice' which is installed into '/utunnel/bin' folder in your UTunnel Access Gateway.
Just follow the steps below to perform the certificate update:
Step 1: Connect to your UTunnel Access Gateway via an SSH client with root privileges.
Step 2: Install any service updates on the UTunnel application running on the server
Step 3: Update the server certificate
4. Step 4: Restart the UTunnel service on the server using the following commands.
Note: Any active connections might disconnect during the service restart.
You can now proceed to connect to your UTunnel Access Gateway. Please note that this process will need to be repeated on the server every two years.
