Configuring DMZ (PIX 515E) to access DNS on public interface

I'm installing PIX 515 on my network, I have three interfaces inside, outside and dmz. On DMZ I have servers with public IP Addresses which are suppose to be accessed over the internet as they are (i.e. no natting, even one to one). i'm currently using my ISP DNS servers, the thing is I cannot access these DNS servers from DMZ but i can do so from my inside network. What could be the problem, attached is my configuration. please assist.

Hi,

first you will need to clear the xlater, then do this;

nat static (DMZ,outside)x.x.x.x d.d.d.d netmask 255.255.255.255 0 0

Assume the IP address for outside is = x.x.x.x and for DMZ = d.d.d.d

Thanks alot this gets me to the internet, does this mean I'll be accessible to the internet via d.d.d.d network?
