Yes there is.
- Click on Firewall Settings icon
- Select Advanced Filtering from the left menu
- Under Wireless Access Point rules, create a rule to block port 53 inbound and outbound. You can also do this under ethernet rules if you want to block hard-wired PCs from using their own DNS settings.
This will block any devices from making their own DNS requests.
You might have to create a rule to allow port 53 requests to 192.168.1.1 (the Actiontec), but I don't think that is necessary.
