Authentication Gateway Software for Wireless?

So what's wrong with DHCP? What's wrong with openwrt? It would be easier to answer if we knew what your restrictions were.

Nothing is wrong with DHCP - the problem is that we are using a lot of features within DHCP, that Chillispot does not provide like: Hostgroups with different options, IP-reservation by MAC, dynamic DNS updating. The main problem with openwrt is that you are restricted to specific hardware - and here is already a huge variety of Wireless hardware in place.

That's why I thought it important we knew why you specified those restrictions. You're not really looking for a solution that doesn't "rely on openwrt", you want a solution that puts the authentication gateway on another computer in your network. That's probably easier than one that _must_ be on openwrt. openwrt is just another Linux OS, so if you've found something that _does_ work on openwrt, you should be able to put it on its own linux box.

How about ZoneCD? I haven't used it, but the reviews I've seen are good. I have no idea whether it will co-exist well with your DHCP, though.

I would think that you could make Chillispot use all those DHCP features - but it might be more work than you want to do.

thank you very much for your advice. I am giving ZoneCD a try. It looks interesting: Live CD, based on Knoppix/Morphix using NoCat as the gateway software. The only drawback is that the system uses an external server on the internet for the authentication stuff. But as they are using a perl based NoCat I think I may be lucky here with using perls Auth::Radius module.
