To set up a VPS with a VPN on Ubuntu,follow these organized steps:

1. Install Required Packages:

   • Open a terminal and install the necessary packages:

     sudo apt install nmap iptables

2. Install VPS VPN Module:

   • Download and install the VPS VPN module (vpsnmp):

     sudo nps install vpsnmp

3. Configure VPS VPN:

   • Set IP Range:
     • VPS typically uses an IP range of 192.168../24.
     • Open a terminal and adjust the IP range if needed.

4. Firewall Configuration:

   • Use Nmap to test traffic:

     nmap -s

   • Configure the firewall to allow traffic from VPS to local machine:

     Use Nmap to scan and block traffic from local machine to VPS.

5. Set Up Nmap Service:

     sudo nano nmap.service

   • Include port for local machine:

     service nmap port 22

   • Start Nmap on local machine:

     sudo nmap

6. Test VPN Service:

   • Run Nmap on local machine to test VPN:

     nmap -s

   • Traffic should be blocked from local to VPS but allowed from VPS to local.

7. Configure Private IP with Port:

   • Set up a private IP with a port for VPN traffic:

     sudo nano private_ip_config

   • Add private IP and port details:

     private_ip 192.168..1
     private_ip_port 88

8. Server Configuration (Optional):

   • Set up HTTP server to serve content:

     sudo nano server.service

   • Include port:

     service server port 88

   • Start server:

     sudo server

9. Verify Configuration:

   • Check VPS VPN module and Nmap service running:

     sudo vpsnmp
     sudo service nmap

10. Troubleshooting:

    • Use Nmap to check traffic:

      nmap -s

    • Adjust firewall rules if necessary.

By following these steps, you should have a secure VPS with a VPN module, enabling data encryption and protection for your application.
