I am looking to set up an SMTP relay for a particular situation, but the exact configuration is not quite right.
In my server room, I have an internal network used for (among other things) connecting up the various servers to the backup server which is normally not externally open (except for updates), cluster heartbeat, etc.
One of the devices on my internal-only network is an APC network management card. It has the option to send email notifications out, however since it is on the 192.168.0.x internal only network, it cannot directly reach any SMTP or Exchange servers.
Several of the servers on the internal-only network also have a NIC that connects externally, so it seems my logical option would be to set up an SMTP relay on one of them, to forward emails from the internal network out to my SMTP or Exchange server IP.
However, I have played around with the SMTP relay application after installing it, and I am not sure exactly how to do it. The instructions I used were from MS TechNet, as the 'spare' server I am testing this with is Server 2003 Standard R2.
Assuming the NMC is 192.168.0.100, and the IP of my external SMTP server is 10.10.10.1 (example), and the server in between has both 192.168.0.101 and 10.10.10.2 as its NICs, how exactly would I set this up? Again, the instructions on TechNet were followed, but it seems like they're more concerned with forwarding emails INTO the internal network.
