Has anyone tried this in the wiki? http://wiki.mikrotik.com/wiki/Manual:Cu ... tspot#Misc
Scroll a bit down to see the "Making HotSpot to authenticate on a remote server" part.

Basically, the concept is that the login page will be hosted on an external server. Then once you click submit on the remote server, the credential will be processed and then resent on the mikrotik router for radius authentication.

I want to use an external server before radius authentication because we have it setup to perform per-authentication tasks, then send it back to the mikrotik router for radius authentication. Then finally give access to the hotspot user.

Has anyone made this work? I tried the sample html verbatim. It does redirect on the remote server, the sending back is not working.
Any thoughts?

I used a remote login page for a while. This page describes what and how I used it.

Great. Thanks a lot for this. I'll update if I have problems.

EDIT: Seems to be working! I'll need to take to the programmers on how to customize this further.
