I need HELP on DNS RESOLVER!

@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..
-
@johnpoz
here they are I block all other dns servers because of I dont want to clients pass pfblocker with other dns servers.

EDIT:I blocked all other dns servers to LAN side from rules section when I do that centos cannot solve that hostname but when I allow all dns servers to lan side centos
Your DNS ! ONLY ! to pfSEnse rule is UDP only ....
Read this https://serverfault.com/questions/404840/when-do-dns-queries-use-tcp-instead-of-udp and start slapping yourself.
Act upon this information (and also activate DNSSEC, it will work this time ^^).
edit : https://en.wikipedia.org/wiki/Domain_Name_System#Protocol_transport - see "DNS Protocol transport"
edit : tip : Instead of "192.168.1.1" as a destination address, use "LAN Address". This will protect you for the next pitfall : the day you introduce IPv6.
-
@gertjan Oh. I change it to TCP/UDP and I can solve it now on centos. And I was enable DNSSEC now and I change To LAN Address on rules section.
But I cannot solve damn edgecastcdn.net anyway.

Possible that you test also with another PC with some Microsoft OS on your LAN - and then use the 'dig' of Microsoft : nslookup.
Just to be sure that your Centos does things as they should.Btw : try also disabling for some time your rule number 3 (the DNS block rule).
-
your rules are not going to allow centos to query anything other than 192.168.1.1 for dns - sothat dig on centos would never work with that rule in place.
-
@gertjan I already disable that rule and mate I cannot resolve this domain on pfsense box too. Its not about rules I think.
-
your trace will show you where you have a problem.. A +trace is exactly what resolver does.. It walks down from roots to the authoritative ns for a domain, then queries an authoritative ns for the domain your looking for for the record you seek..
If you can not resolve thee ns for edgecastcdn.net then no your never going to be able to resolve a record they are authoritative for
Now that you have removed that rule and centos can talk to any dns it wants... Lets see its trace for that record as I posted before.
So how that is resolved

You can see that happen in the trace - and exactly what IP got asked..
If pfsense can not do that - then you need to figure out why.. You can sniff when you run the command and see exactly what gets asked and what gets returned.. On pfsense wan.. If you send a query and don't get a response then the problem is upstream.. Maybe your ISP dicks with dns queries? Maybe you have a network problem talking to the NSers for edgecastcdn.net? maybe they block your IP, etc. etc.

You are NOT talking to roots... When you ask for
dig cs71.wac.edgecastcdn.net +trace +nodnssec
Sniff on your WAN when you do that command... What do you see? You should be able to watch the whole process where does it fail?
-
@johnpoz Am I need to sniff from unbound logs ?

just do a packet capture on the wan for port 53... So you can see exactly what is being asked for and what your getting back
