DNS NOT working for .com domains

[combonix]

Hello Guys,

I have done a multiserver setup using 5 servers(Ispconfig3) , everything is working properly, I had some problems with the firewall but now is solved.
The problem I have now is with my 2 DNS. They only work for UK domain names. When I try to add them on any domain control panel such as goddady or what ever.. it doesn't work for .com names.
I am based in the Uk.. any ideas of whats going on?

i don't understand what you're trying to do , you wanna host your .com domain on your ISPconfig servers ?
that shouldn't be a problem

I have 2 dns within my ispconfig
ns1.mydomain.com
ns2.mydomain.com

When I try to add this servers on any domain control panel such as goddad, they only work whit (.co.uk names)

they only work if I just add an A record.
