I am under the impression that the Sonicwall line of firewalls can be configured to serve as a captive portal device. I am looking for such a device that will allow me to install into a hotel that will authenticate users (If I choose) and then redirect the connected user to a web site on the internet of my choosing.
Is anyone aware of this ability? Is there a better solution? I am looking for a hardware solution that is relatively inexpensive that I can install in hotel environment where I can connect their internet connection to a wireless and wired infastructure to add internet connectivity to the guests.
