DNS Zone Transfer behind a PIX

I'm designing a network configuration for a customer and got a discussion with an IBM engineer about having the primary DNS behind a PIX in located in the DMZ.

The question is :

Is it true that there are problems ( ie is not possible ) doing NAT for the primary DNS because potential zone transfer will fail .

As far as I know this is not true , but I'm asking here for a more knowledgable opinion.

Thanks

Stefano

Re: DNS Zone Transfer behind a PIX

No, you can do zone transfers through a PIX with NAT no problem.
