Simply put, I use OpenDNS DNS servers setup in DHCP and have Dynamic DNS for my home web filtering.
All my DHCP clients receive 208.67.222.222 as DNS. I set my file server up a few weeks ago with 10.1.1.1 (my router) as a static DNS along with the static IP and I noticed web filtering was not working.
Does the edgerouter have it's own DNS servers it resolves if the router IP is used as DNS? Perhaps something easily modified via CLI?
