Does anyone have any interest in captive portal support?
I.e., the ability for users to get redirected to a web page of your choosing
before they're given access to the web as a whole.
This is useful for shared wlan scenarios where you may have unknown users
and you want to either a) tell them who to thank for their access and/or b)
notify them of the usage agreement.
If there's interest, I'm considering hacking something like
http://www.geekspeed.net/wicap/ from perl into php (pf to ipfilter, apache
to thttpd, OpenBSD to FreeBSD).
In the spirit of m0n0wall, I'd try and keep it simple - e.g. the portal page
would be generated from text strings stored in the config.xml file.
