  • Last updated on

The guest access confirmation page allows you to control access to the Internet or other networks by only allowing authenticated users. Unauthenticated users are redirected to a customizable confirmation form on the Barracuda CloudGen Firewall. After clicking Proceed a user in the form LP-<IP Address> is created. Users who have already been authenticated or have been identified by the Barracuda DC Agent are not prompted to log in. The authentication expires after 20 minutes.

  6. Click Send Changes.
  7. Click Activate.

Step 4. Create an App Redirect Access Rule and Pass Access Rule (Optional)

Create an app redirect access rule that redirects the user to the FWauth daemon on Port TCP 446 on the Barracuda CloudGen Firewall, which displays the confirmation page and redirects the user afterwards. Additonally, create a pass access rule that allows HTTP and HTTPS access for authenticated users only. If your access rule set already contains a pass rule that allows Internet access for HTTP/HTTPS traffic, make sure to modify it according to the settings below and place it above the app redirect access rule.

  1. Go to CONFIGURATION > Configuration Tree > Box > Virtual Servers > your virtual server > Assigned Services > Firewall > Forwarding Rules.
  2. Click Lock.
  3. Create an App Redirect access rule:
    • Action  Select App Redirect.
    • Source – Select the source network(s). 
    • Service – Select HTTP+S. Since the user has to use a browser to access the confirmation page, limit the service to HTTP and HTTPS.
    • Destination – Select the destination. E.g., Internet.
    • Redirection  Enter 127.0.0.1:446
    • Authenticated User – Select Any

  6. Click OK.
