I need HELP on DNS RESOLVER!

Oh I see now your getting cached replies from 192.168.1.1, so you can talk to it and it does answer but its not resolving that fqdn..

Why do you have google dns listed in your general setup if your using resolver? Make ZERO sense to do that! If your going to resolve then really pfsense should only point to itself, loopback

@johnpoz thanks for suggest I was delete all dns sources on general setup. And after that I did full pfsense box reboot. And I run dig command again and it shows another output now Im gonna share it with you. LAN and WAN cannot solve ubnt.i.lithium.com but Pfsense box can solve it. Before adding screenshots. I'm giving dns resolver settings.
Network Interfaces: LAN - WLAN - LocalHost
Outgoing Interface: WAN - Localhost
other settings are same with first screenshots.Dig command on centos, nslookup on win10 and pfsense box dns lookup:

Test also this : https://zonemaster.iis.se/?resultid=1bec49eac0feafc5
I guess the zone "ubnt.i.lithium.com" is a mess ......
https://zonemaster.iis.se/?resultid=4308ec04d38fcb73 seems ok -
@gertjan @johnpoz Huh thanks but PfSense box can solve it. Interfaces cannot solve him.
Note: Devices at LAN and WLAN can solve hostname with google dns. But If I point unbound. They cant cannot solve hostname.EDIT: No one needs this information but I want to give it. I can solve "i.lithium.com" and "lithium.com" on LAN and WLAN
-
I know ;)
From my pfSense and one Windows PC, it resolves just fine - although I got back an IP like 72.21.91.97
and after that another IP : 93.184.220.97I went to Services => DNS Resolver Advanced => Settings => Log level and set it to level 3.
Result : https://pastebin.com/51vZi2xX which proofs my Resolver received the requests from my Windows device, and unbound starts to doing "the thing ....".
Btw : my LAN and other OPTx firewall rules :

Hehe I caught something nice in logs. @Gertjan @johnpoz @yellowbrick
I think dns resolver can solve domain. But It cannot stream it to local network. because its cname when I look dns resolver logs. no output about "cs71.wac.edgecastcdn.net" no one try to reach server. They are stuck on "ubnt.i.lithium.com" after that I try to solve "cs71.wac.edgecastcdn.net" on LAN side and pfsense dnslookup and you will see screenshots below no one can solve this hostname pfsense box too.
After that I try ping and nslookup and dig to "cs71.wac.edgecastcdn.net" on lan, wlan side no one can reach because box cannot solve this hostname. But Im getting logs about this now domain.
In this logs I get this IP and I cannot found something usefull same outputs everywhere related this hostname. Then I try to reach this IP.

Not sure when reading the logs, but nslookup on my PC gave an answer.
Check if you have the same.
If some device (PC) doesn't show DNS logs on pfSense, then that device has no DNS (so : no answer!) or that device doesn't use pfSense as a DNS. -
They do have a bit of a problem to be honest with their setup... So the roots for .net only show 2 NS for that domain

Logic
I'm the DNS administrator of that domain.But your test tells me that your Resolver (DNS) works fine.
For what it's worth : when you setup pfSense (that is : assign LAN, WAN) and then you set up your WAN interface any device on your LAN should be able to access the net with any troubles.
Initially : do not touch firewall rules, VLAN's, DNS, nothing.Btw : again : you are not responsible for not resolving of sub domains. The fact that something works on this side of the planet doesn't mean it isn't broken on your side.
Seek contact with the guy that manages ubnt.i.lithium.com - or put in a DNS host over ride. -
looks to me like you can not talk to roots..
-
@johnpoz I can talk with blabla.root-servers.net. I try 5 or 6 of them with random choose.
-
Then why does your trace not get an answer back ??
You should of gotten back the next level - the NS for .net when you did your trace..
example
net. 172800 IN NS k.gtld-servers.net.
net. 172800 IN NS l.gtld-servers.net.
net. 172800 IN NS m.gtld-servers.net.
;; Received 846 bytes from 2001:500:1::53#53(h.root-servers.net) in 106 msMine talked via ipv6 when I did the trace - but ipv4 would do the same thing.. You just stopped at roots..
How did you test talking to them - a ping or an actual dns query?

one question? are you using carp? if so, use the carp vips on dns resolver. for outbound interface you only need localhost.
-
@bahsig No Im not my setup is very simple. 1 WAN(PPPOE) - and 2 LAN (one of them for WIFIaps)
I seeted up my box with that tutorial: https://www.youtube.com/watch?v=RrQrt8r_uYg
And my plugins are pfblocker, snort and squid but I didnt configure it yet.

So your problem has nothing to do with dns it seems like, but more your dns rules?
Lets see these rules for your centos box network interface on pfsense..
