I'm looking for recommendations for captive portal suites for wireless networks. I'm working on a pilot project and we need to be able to do the following:

-- Walled Garden (redirect to us to log in or sign up)
-- Authenticated vs unauthenticated firewall rules
-- Authentication via RADIUS
-- DHCP (probably just call dhcpd)
-- This one's important: must be able to monitor user traffic and associate traffic with a specific user). This one can probably be specified by the logging level of the firewall, though.

I'm familiar with WiFiDog, but **any** other suggestions are welcome, including hardware-based gateways.

Hope this helps.

It does, thanks !
