setting up ISA to allow smtp traffic to exchange 2003
Posted on 2009-05-12
I have a new installation for ISA 2006 and I can't get it to work at all right now. It is frustrating me. This is what I need and this is how I set it up. I need to have email sent from a filtering service accepted and allowed to access our exchange server, SMTP protocol and it will be coming in on two networks into the building, one a T1 and another is a high Speed DSL.
Internal network = 192.168.1.0/24
Exchange Private = 192.168.1.10
External = ISA default setting (two networks, 188.8.131.52/24 and 184.108.40.206/29
Exchange Public 1 = 220.127.116.11
Exchange Public 2 = 18.104.22.168
Address Range MXLogic = 22.214.171.124/24
NAT for SMTP-Exchange1 = Exchange Public 1 to Exchange Private
NAT for SMTP-Exchange2 = Exchange Public 2 to Exchange Private
Access Rule SMTP-inbound
Protocol = SMTP Server
Source = MXLogic
Destination = Exchange Public 1 and Exchange Public 2
Outbound email is working with the All traffic outbound is allowed rule.
The reason is that the email is coming from a filtering service MXLogic and we only want to accept the email from them. this is setup in a SonicWall firewall, an really old one and it is not always working right. So we are replacing it with a new one.
I think that is it. Doing this from memory. Well, I get the Connection Initiated log then a closed connection, and no email delivered.
