I have a router setup in a public area and it is acting as a "hotspot". The access point is on it's own VLAN allowing access only to the internet, and it isolates the wireless clients. The router on the network is a Linksys RV082, and the access point is a WRT610N.
Ideally I'd like it so that when a client connects to the wireless network, when they try to go on the internet they are presented with a splash page of some sort which they have to accept before they can continue. After that internet browsing behaves as normal.
Is this something I can setup? What kind of software/hardware is involved? I imagine some kind of special DNS server or gateway server is needed, but I don't really know where to go from there.
