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, and 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.
