Re: Publishing Exchange SMTP, question

Thank you
probably I made something wrong

I have an Exchange 2007 (single server installation) on 10.0.1.2, my ISP has my MX record pointing on my ISA (ISA is the second server in infrastructure).
So I published 10.0.1.2 to External and added that MX IP. (from Anywhere to 10.0.1.2, requests appear to come from the original client)

But mail are not coming :(
I tried telnet on 25, and after few second I'm getting Connection closed by foreign host.

What could be wrong?

Hi all,

I have two servers:

10.0.1.1 - domain member, ISA 2006 (A)
10.0.1.2 - DC with Exchange 2007 - (B)

(A) has two NICs, second one is 62.168.x.1 (ISP's)

My DNS records are hosted o ISP' dns server.

What should I do with ISA to get my mails from External interface through
ISA and to (B) server
Should I get minimum 2 public IP?
And what about MX for the second server?

Thank you in advance.

P.S. Please explain me that as simple as it can be. I'm new to ISA, but have
Cisco here. On Cisco I can make two Static NAT if that will translate public
IP to internal, then I can make one security policy to let SMTP flow from
outside to my (B) server.
