Preventing circumvention of OpenDNS

Well, I tried the first link. I think the problem for my understanding probably came up that "Block services" for DNS didn't really mean block ALL DNS activity, only DNS requests that didn't originate on the router. I rather thought that blocking DNS would simply block it entirely, even the router's attempts to use DNS. I know that sounds weird now, but it certainly isn't clear on the router interface or in the documentation.

At any rate, I think this worked.  I blocked services for port 53 and if someone's settings are trying to use a different DNS it just blocks it. ... It also seems to block it if it IS trying to use the OpenDNS servers... Would like that second part to function as well. I'll fiddle around a little more, maybe that's the port forwarding part.

PS, not sure what you meant about reaching out to "the author of the article." The one I referenced specifically said that that author and its company would not assist further than what they printed as they can't support everyone's router firewalls.
