Hello! I am trying to setup a web page on a local web server to redirect all traffic from a single MAC address. The ultimate goal here is to restrict internet access, except for a few sites, but allowing those with a specific user/pass to have full access from the same device. Basically this is a kids tablet and they only need access to Netflix but I would like to have full access when I am using it.
What I am thinking is when you try to use the web browser, like say google.com, you get redirected to a page requiring a username and password in order to access the site. Entering in the correct info grants you full access to the internet. I also want the access to expire when internet traffic from that device stops or is idle so that when it is used again to have to login again.
Before anyone suggests, I have considered creating a separate wifi profile but I would have to manually disconnect from and forget the network every time I am done using it.
I have mostly figured out how to redirect all traffic from a specific MAC. But, I don't really know where to start on the web page or how to have the access expire when traffic is idle. Also, which web server would be best for this? uhttpd, lighttpd? maybe a different web server? I have been researching this for the better part of two weeks and scouring the forums here and openwrt, but haven't found a clear answer. If someone could point me in the right direction or give me a few tips that would awesome! Thanks in advance!
