DNS Server and domian

[kurdak]

Hello.
He wanted me to know how I cope with this situation.

The server has ip 192.168.1.3.
Redirected all ports (DMZ).

Domain server: kurkiewicz.dyndns.org.

Domain registered at x.

There is no possibility of forwarding an IP address. So I can not set the domain.

What can I enter in the domain provider dns server in the field, and what steps do I still have my domain to work.
