Re: POP3 Publishing - Publish server on same subnet as source? Workaro

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance




Richard if your clients need to get email from a server on the internet then they need internet access and you need an access rule that allows this type of communication. Your users will need to be either securnat clients or firewall clients. Publishing rules are for allowing access to an internal resource and making it available to the external network.

I read somewhere that you cannot publish a server on the same subnet as the
source IP is this a true limitation of ISA 2006? If it is not possible what
would be a good work around for this?

I am trying to publish a POP3 server internally but it does not work. The
rule does not trap the request at all. The default rule Catches the request
and then denies the request. I am wondering if this is why.

I need to do this because:
All my DNS points at the same DNS name for OWA, POP3, SMTP, etc. Internally
the DNS pointer points straight at the ISA server so that clients do not need
to have Internet access for their mail to work.

Current ISA Rule Configured as:

I created a Mail Server Publishing Rule:
Enabled
Action Allow
POP3 Server
From Anywhere
To IP 10.248.22.19
Listening on Internal Netwrok and Local Host


Client Configured:

When deployed the clients will be using the same DNS name to specify the
POP3 as the SMTP in the mail profile. Currently I am not in production and I
just point at the IP Address for the ISA server in the POP3 specification of
the client mail.
