Google wifi parental controls works well for obvious filth, but has no ability to add custom URLs ore block NSFW content from sites that sometimes have decent stuff like twitter, reddit, etc.
I cannot use xFi because I don't have comcast gateway.
Is my best bet OpenDNS then? Are there directions anywhere?
thanks for your help.
You're asking for very specific capabilites I've only seen in paid parental control software like Net Nanny , Norton Family or Qustodio.
