I do some wifi hotspot installations, and a new client recently asked me if it would be possible to force users to his website when they first open their browsers. After some Googling I figured out that this is "captive portal". It's a free wifi hotspot, so my client doesn't need authentication, just wants users to hit his site first.
So, after much more Googling the cheapest solution I can find is DD-WRT and Wifidog. All you need (as far as I can tell) is a Linksys WRT54G. I'm comfortable flashing the firmware and setting it up. If I can make it work for this client I'm thinking about offering it as an option to future clients.
SO- has anyone ever set up captive portal this way? Is it reliable and easy to support, remotely and securely? If I set my customers up this way will I eventually end up with Linksys Bricks all over the place?
