For the initial setup, you'll have to access the PIX through the
console, since PDM can't be used until the inside interface has been
addressed and turned up.  A  script will walk you through the setup,
including identifying which (if any) end stations from which you will
run PDM.

As for PDM, since you are new to the PIX it is best to start your work
from the command line.  That way, you'll have an understanding of
exactly how the firewall is configured.  After you have the PIX
configured, you might explore PDM to see if it is useful to you.  Most
PIX admins I know use the command line.

Based on the info you provided, you should use public addresses on the
DMZ.  Whether or not you use private addresses on the inside depends
first on how many hosts will be accessing the Internet and second on
your security policy.  If you have more hosts than addresses, then
you'll should use PAT.  If your security policy calls for hiding
internal hosts, then you'll need NAT or PAT.

Hi All,

The decision has been made.
This wednesday I'll meet my Cisco PIX 515E.

This weekend I spent my time reading through the manuals and googling.
I'm learning with the minute.

Two questions however remain.

First: initial setup ( I mean right away from getting the PIX out of
the box).
use PDM (of which i read and hear not very good stories) or log in
through the console?

second...I get two /29 subnets with the co-lo.

setup:

router(provider) ---->  outside - PIX -  dmz ------------> en1 of
Xserve (https, http)
                                               |
                                               inside -----------------> en0 
of Xserve (sshd, serveradmin, mysql)

question...use the public ip's without nat for the inside,dmz and
Xserve interfaces? or use NAT, and private ip-addresses "after" the
PIX?

i'm planning to set-up multiple HTTPS sites, and will need the public
ip-addrresses for that.

Any advice is welcome
