Here are the instructions to open necessary ports for a VPN server on Ubuntu:

Steps to Open VPN Server Ports on Ubuntu

1. Access the Terminal:
   Open the terminal on your Ubuntu system or connect via SSH if managing a remote server.

2. Update and Install UFW (Uncomplicated Firewall):
   If UFW is not already installed, install it using the command:

   sudo apt update
   sudo apt install ufw
   

3. Allow Required Ports:
   SoftEther VPN and OpenVPN require specific ports for communication. Run the following commands to open these ports:

   • SoftEther Ports:

     sudo ufw allow 443/tcp
     sudo ufw allow 5555/tcp
     sudo ufw allow 1194/udp
     sudo ufw allow 500/udp
     sudo ufw allow 4500/udp
     

   • Other Common VPN Ports (if applicable):

     sudo ufw allow 1701/udp
     sudo ufw allow 1723/tcp
     

4. Enable the Firewall:
   After configuring the rules, enable UFW to apply the changes:

   sudo ufw enable
   

5. Check the Status:
   Verify that the ports are open and the firewall is active:

   sudo ufw status
   

6. Test Connectivity:
   Ensure the VPN server can be accessed from your devices using the allowed ports.
