Features for the Captive Portal

In a previous post, I talked about my quest for a captive portal which supports per-user download quotas (and also explain what the heck a captive portal is).
Here's a list of features which I was looking for in the Captive Portal:
- Free!
- Web-based administration
- Users need to login before having access to the internet
- Volume-based accounting – as opposed to time-based accounting. User quotas are determined by the amount of bandwidth they consume.
- Daily (or some other time period) reset of quotas
- When the quota is consumed, internet access is blocked till the quota has been reset.
- Support for DNS and HTTP caching
Existing options
I surveyed a number of the router firmware/linux distro options, including DD-WRT, OpenWRT, Gargoyle, Tomato, pfSense, IPCop, Untangle, etc. None could do the job out-of-box, or suggested a relatively straightforward pathway to implementation.
Most offered some kind of QoS bandwidth throttling, and or limited quota system, but not all the features I needed in one.
The only out-of-box software that seemed to be a perfect fit was the popular Windows hotspot program FirstSpot. It is however prohibitively expensive.
After alot of research, I finally decided to go with an open-source PHP/MySQL-based hotspot solution called EasyHotSpot.
In my next post, I'll talk about EasyHotSpot – what is it is, what it does for you, and what it doesn't.
