Your firewall also needs to be able to pass WebDAV traffic. Firewall-1 and
other products like it can filter out WebDAV traffic which will cause your

Hi,
if you want to open ports for your users to be able to send mail you have
to open the following ports:
SMTP (inbound/outbound mail): 25
(optional POP3 / IMAP4)
pop3: 110 (insecure, password sniffer possible)
or use 995 if you prefer to use ssl
Imap4: 143 (insecure) of use 993 foor imap4 ssl

Exchange 2000 Server
I recently got a Cisco PIX and I need to know what ports are absolutely
necessary to allow inbound traffic through the firewall for people to be
able to send mail in, access OWA, etc. I am reading that port 135 needs
to be allowed inbound but due to all
a waste of time.
As for other ports,
SMPT: 25
OWA: 80 or 443
The rest should be firewalled.

Its probably been doing it all along, but I've been monitoring our
firewall this morning, and found that when our SMTP server connects out
to some other SMTP servers, we see a TCP 25 connection as expected, but
we also see a TCP connection around port 4460 or similar, which our
firewall blocks.
I believe 4460 is unassigned. However I think that Oracle's Portal server
users port 4460 for SSL.

You could set up IPSec tunnels between this server, the backend server,
and the DCs. You could even limit those to only the ports necessary for
it to function. Then you'd need to open the firewall for type 50
traffic (ESP IPSec), port 500 TCP for IKE (Key Exchange), and port 88
TCP for Kerberos
At the very least, you should run URLscan on that machine so that it's
not hacked immeadiately.

Besides, it isn't as simple as just opening some ports. Exchange does some

Subject: OWA/Exchange Ports Security anyone?
Could anyone tell me if the below can be considered as an acceptable
approach to OWA implementation.
1. OWA/IIS resides in the DMZ
2. The only port
You can set some of the ports as static (IS, DS, MTA, etc.,) but you cannot
assign a static port to UDP Push Notification. If ports1024 are blocked,
your Outlook clients might be able to send and receive mail just fine, but
the blocked Push will prevent the view from refreshing. This results
Well I believe I'm finally starting to understand. Even if we opened up the
ports as described in FAQ 3.24 and assigned static ports on the Exchange
server for the DS and IS, it would also be necessary to open the UDP ports
1024-65535 up for clients to get notified of new mail.
Don't get me
And even after opening those ports it's entirely possible you'd experience a
greater number of dropped UDP new mail notifications with that connection
method than you would with VPN (at least that's been my experience).

2. The only port that can get to it from the Internet is SSL/443
3. OWA/IIS can talk to the Exchange server on the internal network via two
statically mapped ports

No security consultant I know is going to open holes in the
network from the DMZ to the Internal network. Being
proficient in both Exchange and Security
I think the real point here is that if you are concerned about the hole that
you will be opening from your DMZ-LAN with OWA, or you are concerned with
the hole you're opening by placing OWA on your LAN and openeing SSL through
to it then you should really be using a VPN and neither of the OWA

Hmm... I don't know. I think there are instances where a box in the DMZ
communicating with the internal network makes sense. I
How do you rate using IPSec between FE and BE?

I will somewhat agree
I believe that would be a valid solution. At least that is an encrypted
communication path.
