I've been to a number of public access points where any DNS request is forwarded to a disclaimer page. Some of them require you to sign up for a free account and sign in before use.
I don't really know what this kind of DNS routing is called or how to implement this type of interface but I was curious to know if a package is available for OpenWrt that fits the above criteria.
Any help would be much appreciated. If not OpenWrt then what should I look into next?
Thank you in advance for any suggestions.
