Should I use PIX PAT or NAT 1

[vexxed]

I'm learning the PIX and I wanted some advice. I have a DMZ and an internal network separted by a pix. I want to pass only the following traffic from the internal network to the DMZ servers: terminal services (3389) sqlnet (1521), mapped drives (137,138,139)
Can I accomplish this using PAT and only use the outside interface on the pix or do I need to use NAT and esablish a pool of addresses on the exrternal interface?
I can't find any documentation at cisco about what protocals you can't use with PAT. If anyone knows of a doc, please post.

thanks

Alot of companies use NAT. See the link below to help u get started.

Thanks, yea, I read that article. I was in a rush to implement this PIX and since I got noreplies to the question I waited a day and did some testing first. Netbios filesharing works through the PIX with PAT if only one host is doing it at a time. Two hosts and it all buggers up so NAT was the only way to go. the other stuff works as well.
