Well first of all, I wanna say hi to everyone because i'm new to this site. Really great site to find information about ISA server. ;)

OK, so I've got some question regarding configuring mail and web server for my company and, of course, ISA server. I'm not sure about some part's of the configuration so I need you help ! :)

Well anyway, this is my first configuration of this kind so be reasonable ! ;)

I will have mail and web server and ISA server will serve as firewall and DMZ zone for those two server's.

Here's the picture of my infrastructure:



Now, I have configured everything but i'm having problems with ISA..

I have applied rule for sending mail to mail server, that is in DMZ, but i'm getting this error:

"Description: Server publishing rule [my rule] failed because there was no valid network listener. For requests to reach the published server there must be a network relationship between the selected listener networks and the published server. Location 325.934.4.0.2167.887.
For more information about this event, see ISA Server Help.
The failure is due to error: 0x8007000d"

I have created DMZ network and created network rule that says "Source Network - DMZ to Destination Network - External and Network Relationship - NAT".

I dont know what i'm doing wrong ?

Another thing is that my mail server can't access internet so i can't send e-mails. 

Thank's for you answers !

Have you tried to set the Network rule to "Route" insted of "NAT"? Is the same error ocuring when Route is set within the relationship?

Have you defined a network rule from Internal to DMZ (or vice-versa)?

Ok, I think we need some details of your publishing rules, in addtion to your network rules - can you provide these?

You forgot the network rules, those are of biggest interest.
