This was my finding too, so I scrapped the entire WiFiDog authentication system and wrote my own ticketing system. The one issue it has that is annoying is that it is difficult to do QoS traffic shaping and control. When you have random users on the network, some will hog the bandwith with P2P or streaming vids. There is also a little bug in the captive portal that allows users bypass the IPTable restrictions if the same token is submitted twice. to I think has been fixed in the most recent version of the captive portal.
<div>I put the entire ticketing system on a WRT54G and it has been working pretty well for the past 3 years.<br /><br />
