Can not resolve a DNS

johnpoz

if you have a ACL setup correctly then you for sure should be able to get the roots from pfsense and then your dig +trace command should work, or atleast return with the roots, it might fail after that but its shouldn't come back blank like you were seeing.

when I Disable Auto-added Access Control nothing gets resolved I had to uncheck it

johnpoz

this is because if you don't use the auto, you have to create your own!!! Which you said you did, I posted a screen of mine as example..

johnpoz

you don't need the ipv6.. Shoot I should of hid thouse.. Could you please delete that pic, I will delete mine and repost with thos hidden.

You need to put in the network your using.. What network are you using - if for example 172.16/12 then my acl would not work for you..

Your using 192.168.0/24 right.. So if that is the only network you query pfsense from then that would be in your allow list. So if you put in 192.168/16 like I have then it should work.. So your still not getting the root servers when you do a +trace from your client on 192.168 network??

Do the drill command on pfsense then.. Lets see where its failing.

Chrismallia

Sorry John for posting the pic I removed it from my pc and post. My network is 192.168.0.1/24

johnpoz

Oh not on you at all!!! It was my bad for not seeing I posted a global IPv6 address… Thanks for removing it.. I reposted with the ipv6 obfuscated. In the big picture prob not a issue at all.. Normally I wouldn't care.. but as you can see from my neg karma number. Some people don't always like my posts ;) And vs doing the -1 which would be their right.. They hit it an hit it and hit it.. I know for sure about 60 of those came from 2 guys..

So with the ability to rent the very large botnets, I wouldn't put it past some people to think its funny to run a ddos against.. Yes I have my tinfoil hat on while typing this..

192.168.0.1/24 is not a network btw, that is a host address the 192.168.0.0/24 ;) So if your putting in ACL you can put in 192.168.0.0/24 or 192.168.0.0/16 is the full 192.168 rfc1918 space.

Chrismallia

DW John remember the guys that try to help in this world get the slapped back instead of thank you, I read a post with a guy admitting was longing to pick one out with you and accused you that you dont know what you are talking about llooolll Some should learn from you. Now sorry for asking but should I go to Command Prompt in pfsense and type drill melita.com?

yeah you need to -T with the drill command

drill -T melita.com

This should give you the full trace like dig would do..

So for example running it on my pfsense just now.

So doesn't look like your getting any answer from the NS for that domain.

melita.com. 172800 IN NS ns.melitacable.com.
melita.com. 172800 IN NS ns1.melitacable.com.

Query them directly!!

Their IPs I gave ealier, but here they are again.
ns1.melitacable.com. 86088 IN A 212.56.128.196
ns.melitacable.com. 86088 IN A 212.56.128.132

so from pfsense

drill @212.56.128.196 melita.com

Those are not from the commands I gave you..
