know that it is not a webserver, but it would be an interesting feature!
now already we have it thus, but we used a Web server with apache for all nodes of network, always showing the same page for all nodes.
My intention is that each node has its own page and contains he himself; and the hotspot system is very complicated, and nat & redirect is easy.
Present scenario:
-Client open a browser and open ex. google page.
-selective nat actue only w Internet content (exclude internal nets).
-dnat & snat masquerade to client and send the conection to our server.
-on apache server the errorpages (404) redirect to our index.html
-all nodes of the net work w same nat configuration.
