I'm kind of new to iptables, andw hile I gather that it is very powerful, I'm not sure of how to use all the features. Would someone please let me know if this is feasable? Or am I better off just using a captive portal solution (which one?!)
Have an iptables rule that checks an outgoing mac address from the wireless interface against a local file (list of mac addresses). If it isn't in the list, redirect HTTP connections to a local php page. Allow them to click "ok" on a page, which will add their mac address to a file, using php. Once this happens, they'll pass through the iptables rule that checks to see if their mac is listed in the file, and continue on to the internet via NAT.
Or am I just making this way to complicated?
