Configure captive portals

Captive portals are commonly used on public-access networks to require users to login or accept terms and conditions before accessing the internet.

Note Captive portals are available on the AnywhereUSB PlusW Wi-Fi enabled model only.

To configure captive portals:

    Traffic received on this interface's network device will not be forwarded unless the client has been granted access.
