DNS not responding

Does that mean you have a dynamic IP? You shouldn't host a DNS server on a dynamic IP!

 

Oh no sorry my bad, i have wireless with stable connection and static IP. Sorry for last post I don't checked it. But in post #10 I said with static ip.
Thanks

 

Something is blocking port 53 (TCP and UDP), maybe a firewall, router, or even your ISP?

 

I think ISP is blocking DNS but don't know why. Firewall is open, router is okay everything is fine so problem is not on my side. I have to contact ISP. Thanks falko, Toucan... for help.
