Network Firewall

I’m not sure if this is the right category, but anyways. I am trying yo set the cis firewall up on my d-link dir-615 router. When i put the dns servers into the box on the router wep page and hit save, the internet does not work. If i search something it comes up this web page can not be displayed.
the dns servers i have put in are

Primary DNS : 156.154.70.22
Secondary DNS : 156.154.71.22

Hey and Welcome to the forum!

I think you should try to add those addresses Secure DNS for Router DNS, DNS Setup Instructions - Comodo in the router.

Have you tried inputting the IP addresses in the networking setup on your computer?

Secure DNS for XP.
Secure DNS for Vista/Windows 7.

Also, SecureDNS is not required for the firewall to work.
