Making a new rule for DNS 1,2,3 from my routerI don't

Let me say I’m new to this forum and Comodo Firewall. I don’t know what Tags are so it’s blank. I have a Linksys BEFSX41 and in it you have under status DNS1,2,3 with a number 68.105.28.11, 68.105.29.11 and 68.105.28.12. Are these considered addresses? I’m trying to set up an internal rule for these in my Comodo Firewall cause my computer talks back and forth to these for UDP. I had ZA Free but it was a dog, but was easy to set this up for these DNS items. I did the network setup and it seems OK except it’s blocking my computer from talking to my router on these DNS items. I believe it’s port 53. Any help would be greatly appreciated. There are two computers on this network and my IGMP is being blocked. I understand these DNS are servers and they do alot of talking and it’s all being blocked. If I can’t get this fixed I’ll have to go back to ZA and I can’t stand that dog.
