Hi thanks for your reply and testing it out MM that is strange cos I always had this problem on different installs and different hardware, I wish I can resolve this as melita is our ISP here and we need it.

A My friend johnpoz love to hear from you :) I get a page error This site can’t be reached
-
no with an actual tool that does a query.. page can not be reached doesn't mean your dns didn't work..
Use drill like dok did, or dig or host or nslookup.. A tools that actually does a query that you can see the results in.. For all you know your browser is looking in its cache that it got back a nx before.. and has to wait for the neg cache to expire..
Your browser has a dns cache, your OS dns client has a cache, pfsense has a cache. You need to understand what is exactly happening.. And if you can not query or just some browser error, or maybe the site failed..

when I do dns lookup melita.com it results the ip fine. when I ping melita.com from a windows cms I get >ping melita.com
Ping request could not find host melita.com. Please check the name and try again. when I ping the ip it pings fine -
windows "cms" ?? what is that? content management system? did you mean command prompt?
what are you using for dns lookup - what tool? And what are you doing the query too? Maybe your machine is infected with something and hijacking connections??
Please post your ping command and your "dns" command output.
ping melita.com

ipconfig /flushdns

Hi I hit the s by mistake I meant CMD. There is nothing wrong with the machines I tried the same on a fresh install laptop with same results, now when I change my dns settings manually in windows to google it opens the site fine and this is happening across all my machines phones and I also have a linux Manjaro pc same problem. I used dns lookup in pfsense and it resolves it fine but on clients no
C:\Users\Chris>ping melita.com
Ping request could not find host melita.com. Please check the name and try again. -
but if you do a dns query via nslookup or dig or drill or host from that same machine your saying it resolves??
If so then flush the machines local cache and try your ping again!!
from your cmd, ipconfig /flushdns
dns query for it - does it work?
then ping it..
If ping says can not resolve then you got something wrong on the machines built in dns client.
-
I flushed it but same problem I did nslookup in cmd
C:\Users\Chris>nslookup 212.56.128.204

I am sure it is not my machines/devices as using google dns on the machines or replacing pfsense with a different router solves it

Yeah sure looks like your having a issue resolving it.. Do you have pfsense using itself for dns?? Or do you have it using something else?? Thought you said your dns query for it worked?? From that you first got a timeout, pfsense was trying to resolve?? Then you get back serv failed.. Which normally means could not talk to the NS it.. So is psfense using itself, ie this will use resolver out of the box in resolver mode and pfsense asking the resolver for stuff it wants to resolve.
nslookup is not as good at helping debug dns issues as dig is. What I would suggest you do is install dig on your windows box, or use linux with dig or drill and do a trace.. This will talk to the roots and walk down the tree just like unbound does in resolver mode. This should tell you where there is an issue.
so example..

You can just download dig for free as part of bind, then just install the "tools"
https://www.isc.org/downloads/Or just do it direct from pfsense with drill
[2.3.2-RELEASE][root@pfsense.local.lan]/root: drill -T melita.com com. 172800 IN NS h.gtld-servers.net. com. 172800 IN NS l.gtld-servers.net. com. 172800 IN NS a.gtld-servers.net. com. 172800 IN NS e.gtld-servers.net. com. 172800 IN NS f.gtld-servers.net. com. 172800 IN NS d.gtld-servers.net. com. 172800 IN NS g.gtld-servers.net. com. 172800 IN NS j.gtld-servers.net. com. 172800 IN NS b.gtld-servers.net. com. 172800 IN NS m.gtld-servers.net. com. 172800 IN NS k.gtld-servers.net. com. 172800 IN NS i.gtld-servers.net. com. 172800 IN NS c.gtld-servers.net. melita.com. 172800 IN NS ns.melitacable.com. melita.com. 172800 IN NS ns1.melitacable.com. melita.com. 86400 IN A 212.56.128.204 melita.com. 86400 IN NS ns1.melitacable.com. melita.com. 86400 IN NS ns.melitacable.com.If it fails - you can u the verbosity with

No this not the dig I showed you.. Do a full trace.. and forget any dnssec stuff.. Maybe that is what is failing for you, which is why lets do it without the dnssec, etc.
dig +trace +nodnssec melita.com

that is your full output??
Is 192.168.0.1 pfsense? And you have it resolver mode? It should of atleast given you the root servers.. You got something wrong..
Try it with just the +trace option
dig +trace melita.com
Also dig NS what does that give you back?
