Server Publishing

[mitzysman]

Is there anything in ISA 2000 that would be keeping this from working. I doing what I read on ISAserver.org and I can't for the life of me get Smtp or pop3Secure to forward to an internal server.

I using the same port on ISA and the Email server ... just nothing happens.

I have opened the port on the IP Packet Filters as inbound as well

Can seem to get any ports to redirect to any applications in any server on the inside

Any thoughts ?

Go into isa management and run the secure mail server wizard.

Normally, this is pretty straight-forward task. Either run the Secure Mail Server Wizard, or do it manually.

When doing it manually, you need to know the IP of the internal server (mail server that is) and of your ISA Server on the outside. Also, ISA Server must have bound this IP Address to it's external NIC. Mapped server protocol is SMTP Server of course.

Troubleshoot:
[ul]
[li]Make sure that you are able to reach your mail server from your ISA Server - issue a [tt]telnet 192.168.1.25 25[/tt][/li]
[li]If above is ok, issue a [tt]netstat -a -TCP -n[/tt] to verify that ISA is listening for incoming SMTP-requests. The output should read something like this (given 1.2.3.4 is your external IP): [tt]TCP 1.2.3.4:25 0.0.0.0:0 LISTENING[/tt][/li]
[li]If above is ok, issue a telnet to 1.2.3.4 from some external machine and verify[/li]
[li]Verify MX-record on some external machine, that the result is pointing to correct IP[/li]
[/ul]
