How To Redeploy On-Premise VPN Server

This guide will help you to redeploy an On-Premise server from UTunnel VPN.

1. Connect to your server via SSH with root-level privileges and execute the following command to stop the UTunnel service:

sudo /utunnel/bin/utnservice stop

2. Access your UTunnel Dashboard by logging in to your UTunnel account.

3. Click on the Server tab to access the on-premise server for which you want to change the IP address.

4. Select the "Redeploy Server" option from the left side menu.

5. Type in the IP address you want to update to your UTunnel VPN server in the Enter new IP Address field and click the SAVE CHANGES button at the top right.

6. Hit the REDEPLOY button to confirm redeploying the server.

7. Now you will receive a token to register the utnservice. Copy the token and proceed.

8. Now, connect to your new server via SSH with Sudo access. After the successful login, execute the following commands:

sudo mkdir /utunnel && cd /utunnel

sudo wget

sudo tar -xf install_bundle_20.tar

9. In the next command, you need to replace YOUR_REGISTRATION_TOKEN with the registration token you copied from the Server Details page (Step #8).

sudo /utunnel/bin/utnservice register YOUR_REGISTRATION_TOKEN

10. Now it's time to start UTunnel Service on your server. Run the following command for the same.

sudo /utunnel/bin/utnservice start

11. Make sure that inbound connections to the following ports are allowed to accept VPN connections.

Ports used for OpenVPN connections

  • TCP 443
  • UDP 443
  • UDP 53 (if scramble VPN is enabled)

Ports used for IPSEC connections

  • UDP 4500
  • UDP 500

Ports used for managing UTunnel services like live sessions, firewall, and site-to-site tunneling.

  • TCP 38081

Now your server would be ready to accept VPN connections. Invite users to your server and start using your VPN.
