A VPN carries selected traffic through an encrypted tunnel to a VPN server. Start by connecting one device, then check what that device's browser exposes.

## What you will accomplish

Set up a connection you can inspect instead of relying on a badge.

## Do it now

1.  ### Install the correct app
    
    Use the provider's official website or your device's official app store. Check that your operating system and subscription support the app.
    
    **Check:** The app's publisher matches the provider you chose.
    
2.  ### Connect deliberately
    
    Choose a server and wait for the app's connected state. Check whether split tunneling excludes your browser or any important app.
    
    **Check:** You know the selected server and which apps should use the tunnel.
    
3.  ### Observe this browser
    
    Open the connection check. Record a baseline only if it is safe on a trusted network, then compare after connecting. Check IPv4 and IPv6 separately.
    
    **Check:** You can explain the observed route without treating it as a complete security assessment.
    

## Check the result

You can explain the observed route without treating it as a complete security assessment. Change one thing at a time so you know what made the difference.

## If something does not work

If browsing fails, try the app's reconnect function or a different supported server. Follow official support instructions rather than disabling security controls at random.

Background and further explanation

## What the tunnel changes

The local network ordinarily sees a connection to the VPN server rather than the same direct destination connections. The VPN operator becomes another party you trust. HTTPS remains important between your browser and the website. A browser extension, full-device app and router configuration can cover different traffic.
