How to block port 53 on Archer c2 (AC750 v1)
Hi!
I have an Archer C2 (AC750 v1) and I want to block port 53 on all hosts and all targets except the cleanbrowsing.org dns servers' IP addresses. I cannot figure out the way how to do this.
This is a home network for my family and I have four teenage boys. I use cleanbrowsing family filter but I want to restrict port 53 only to cleanbrowsing's DNS Ip addresses to prevent circumventing the whole system.
Thank you for any help!
