Still learning

I have an existing network that I am installing a pix firewall into. I am putting the web and email servers in the middle of the fire wall to give them some protection. I am trying different sinarios to try to keep from having to change the ip addresses of these servers. Its a real pain getting network Va to change to a new address. I own a class C and the web and email are at 3 and 4 . Can I do a static translation from a public class c address to a private class a address? What are the commands?

Re: Still learning

First, the web servers and mail servers etc. should go into the DMZ that you create. (just another interface). As far as addressing goes you can use either publics or privates in your DMZ, it doesn't matter. What does matter is rather or not you NAT. If you are using privates then you need to set up a NAT

global (outside) 1 [NAT Pool]

nat (inside) 1


static (dmz,outside)

nat (dmz) 0 0 0

The static make the network visable on the outside, the NAT statment says don't NAT in the DMZ.

I suggest you reaed up on this and look at as many examples as possible before you do anything to drastic.
