Kevin,
PIX is not part of the R&S lab, but the answer to your question seems
simple when I look at your config. The PIX will not allow any traffic from
a lower security level to a higher. So when you do not configure it, your
outside will not talk to the inside or dmz. At this moment you will see "no
xlate" messages in your log when you try to access the dmz or inside from
the outside. You need to tell the pix to allow traffic from the outside to
the dmz. Play with the nat command's, because what you need is a "nat (dmz)
0" line. Another method is to use the "Static" command, which will do the
same.
you can also take a look at:

I need some help. Here's my layout.
Inside net-------router1--------pix--------router2-------Internet
|
|
dmz----ftp server
All my pix interfaces have valid ip addresses and so does the ftp server on
the dmz. (no nat'ing happening on pix). Nat'ing is taking place on
router1.
From the inside, I can ping and ftp to my ftp server in the dmz. From the
outside I can't.
When I ping from the outside, my access list that's applied to my outside
interface is incrementing but not the acl on my dmz interface. Plus I
never
see any reply packets coming from my ftp server when using debug on my pix.
I can ping my ftp server from the pix.
Since I can ping and ftp successfully from the inside, my dmz acl is
working
fine.
Does anyone have any ideas why traffic from the outside. Attached is my
config and I've replace the good ip's with private.
Thx,
kevin
