interface spreading

Hi,

I have several hotspots installed in Spain. Lots of them are MT’s with a wireless interface, so I put hotspot service in this interface. My MT hotspot broadcasts multiSSID using VirtualAP feature.

In this HOTSPOT I want to show a different login page to a user depending on which ESSID this user connects. I can put one hotspot service by virtualAP, however it is not the solution what I want. I choose to put wlan1, vap1 and vap2 (vap = virtual AP) in a bridge named HOSPOT, and I put hotspot service on this interface.

Yes, I recollect all MT variables in the login.html and I send them with a form to a central web server. My web server executes a PHP script. This script can shows a custom page using identity and interface name. It works fine in a unique hotspot because in “interface name” variable appears the name of the virtualAP (wlan1, vap1, vap2).

If I want to increase the wireless covering, I put another MT which works as Access Point. This device has three ESSIDs: wlan1, vap1, vap2. There is a switch between my hotspot and my AP where both devices are connected. I want to spread these interface name using some way.

My question is how I can spread interface name where a user connects, from AP to HOTSPOT. Any suggestions?

Thanks,
Santiago
