Modifying Captive Web Portal - Black Box LWN602A User Manual

5
HTTP Client
After a guest agrees to the acceptable use
policy, fills in the form, and submits the
registration, the SmartPath AP moves the
client's MAC address from a quarantined list
to a registered list.
To enable the captive Web portal to forward DHCP and DNS traffic from unregistered users to its internal servers, click
Configuration > Advanced Configuration > Authentication > Captive Web Portals > New, and select Use internal DHCP and DNS
servers on the SmartPath AP. By default, the internal DHCP server issues leases with a ten-second lifetime, and if a client with a
nonexistent lease requests a lease renewal, the SmartPath AP responds by broadcasting a DHCP NAK. You can change the
SmartPath AP response so that it sends a unicast NAK or ignores the request completely (Keep Silent).
9.3.3 Modifying Captive Web Portal Pages
Black Box provides .html files and images for use on the captive Web portal server and a tool in the GUI to modify the supplied
text, colors, and images to better suit the needs of your organization. The various file names and their purposes are as follows. An
example of the default web page components is shown in Figure 9-14:
• registration.html (the main login page for self-registration)
• authentication.html (the main login page for user authentication)
• auth-reg.html (the main login page for either self-registration or user authentication)
• eula.html (the login page for the acceptable use policy)
• success.html (the page that appears after registering successfully)
• blackbox_3d.jpg (default main image on the web pages)
• failure.html (the page that appears after an unsuccessful registration attempt)
• blackbox_hex_light.jpg (optional background image)
• reg.php (a file that the SmartPath AP generates automatically and stores on its internal Web server)
• blackbox_hex_dark.jpg (optional background image)
• blackbox_spacer.png (a transparent image that provides space at the top of Web pages; size 200 x 103 px)
• blackbox_logo_reverse.png (Black Box logo with white text at the bottom of the Web pages; size 111 x 48 px)
• blackbox_3d_bg.png (an image that provides blue filler as background around the main image; size 5 x 5 px)
• blackbox_logo.png (Black Box logo with dark text; size 111 x 48 px)

appropriate user profile to the registered user
and forwards all types of traffic to the rest of
the network, as permitted by firewall policies
assigned to that user profile.
