Subject: Problems switching from dedicated IP to Firewall

To: <sims>

I've been running SIMS since September last year and never had any problems
(though it had it's own IP address). Three weeks ago I moved and no longer
have access to all the IP addresses I had before. So I configured a Quadra
950 (8.1, OT 1.3, 28M) with IPNetRouter (IPNR) connected via ADSL and have
placed the other three machines behind it on a private ethernet network. I'm
able to ping all the machine locally and they all access the web correctly.
SIMS is running on a Quadra 700 (8.0, 20M, OT 1.2) and is receiving mail but
it never gets placed into the local mailboxes and after the scheduled period
bounces all messages. It seems obvious to me that I have something
configured wrong with SIMS.

Below, between the ==== I have included the typical bounce message.
My IP address has been assigned to the domains and
by my ISP. IPNR has been configured to pass ports 25 and 110 to SIMS and
they both work as I can telnet to it through either port. I can even access
the SIMS web interface from my local machines (I haven't set it up to access
from outside the network yet).

I need some advice on how to fix this as I do not understand what I've done
wrong. If more info is need to figure this out, I'll be more than happy to
provide it.

Thank you.
