This flowchart shows the step-by-step process of how a VPN connection is established, how data is encrypted and sent through the VPN server, and how responses return securely to the user.

Step-by-Step Trace - 9 Steps

Step 1: User requests to connect to VPN

Step 2: Check if VPN server is reachable

Step 3: Establish secure encrypted tunnel

Step 4: User data is encrypted and sent through tunnel

Step 5: Data reaches VPN server

Step 6: VPN server forwards data to internet

Step 7: Internet sends response to VPN server

Step 8: VPN server encrypts response and sends back

Step 9: User receives decrypted data
