so here is my issue.
I wanted to test and possibly implement this at our school.
I have about 150 chromebooks on a subdomain - controlled via a ubiquiti ER PRO 8 Router. ( 192.168.17.x /24)
now I changed the DNS settings on the router to the OPEN DNS settings, after setting up an account with open dns.
when i tested with couple of devices (5) it worked awesome.
School started monday, everything was fine..and then about mid day..every one in our school including people on other domains started getting " Unusual activity error from Google which requires a captcha verification" This captcha verification was doable on desktops..but on chromebooks the captcha wasn't showing up..oh god the horror!!.
So i changed the DNS settings back to Google DNS. And connected the Goddam barracuda back again. ( i hate the barracuda T.T). Its slow as hell.
I am new to this..am i doing something wrong...or does the issue stem from the fact that open dns is a public service.
but still i thought it should be a safe service.
Any Help would be greatly appreciated.
