I'm trying to block Google public DNS lookup on the DGNM-2250. My Chromecast has them hardcoded and I want to block them. These are 126.96.36.199 and 188.8.131.52.
On my previous router I was able to setting up static routes but I don't see anything like that on the DGNM-2250 setup. Has anyone tried to do this? Also, would it be possible to block these 2 IP's using the router firewall?
