dmz mikrotik with sonicwall

Hi guys!

I´m not english speaker so sorry if I have any mistakes.
I´m trying to build a dmz so I have a mikrotik rb951g and a sonicwall nsa. The mikrotik is the router and the sonicwall will be the firewall between the public servers and the private network.

My first problem is how to configure the mikrotik router and the sonicwall for making both work together.

And the second problem is to make the dmz.

Any Ideas?
