Captive Portal – Click to Continue Method

Zyxel_Claudia

USG FLEX H Series Firewall has added a new authentication option to its Captive Portal: the Click to Continue (CTC) method. This alternative to traditional username-password login simplifies the onboarding process, especially for guest networks or public Wi-Fi environments.

1. What is Click to Continue?

Traditionally, Captive Portal requires users to authenticate by entering a username and password on the login page. With the new Click to Continue method, users can simply click an “Agree” button to gain access to the internet.

This approach is ideal for:

• Guest networks at cafes, hotels, or public venues

How It Works:

• When a user connects to the network, the Captive Portal landing page appears.
• Instead of filling out credentials, the user just clicks “Agree”.

Access is granted instantly, without authentication

2. Viewing CTC Users in the Firewall

Once users log in using the Click to Continue method, they are automatically assigned to a default built-in user account named "CTC users".

To monitor active CTC sessions:

• Go to Network Status > User Login > Login Users
• Each connected user will be shown under CTC users, with their individual IP address
  

3. Configuring the CTC User Profile

The built-in CTC users profile can be modified to control:

• Lease time
• Reauthentication time

To adjust these settings:

1. Navigate to User & Authentication > User/Group > User
2. Click Edit to customize the session behavior
   

This gives you control over how long users stay connected and how frequently they need to click to continue again

4. More Information of Click to Continue

While Click to Continue offers simplicity, it comes with a few important caveats:

No Customization of Landing Page

As of the current firmware release, the landing page for Click to Continue cannot be customized. Users will see a default interface with the agree button. Zyxel plans to enhance this in future releases.

Click-to-Continue vs. Simultaneous Access Logon

Limiting simultaneous access logons does not affect click-to-continue users.
