If you use public addresses, you'll either have to obtain a new range of public ips or 
subnet your existing range.  If you have to subnet an existing range, my opinion is 
that using private addresses and doing NAT will be easier.

I'll leave the debate about the relative security of Natted private addresses versus 
public ips in the dmz to others in the list who have definite opinions about that 
issue.

Hi all,

I need to create a DMZ on my firewall and I have been thinking how I should
address it, the possibilities are:

1. Use public Internet addresses.
2. Use private addresses and do the required translations on the firewall.

What is the best to do? What are the pros and cons of each addressing
method? I would like to hear your opinions on the subject.

Thanks in advance,
F�bio Rocha.
