I have just set up a DMZ and put one machine there which runs an application that sends out email notifications through SMTP. So I created a packet rule to let out SMTP: DMZ =SMTP=> ANY, to no avail.
It turns out the SMTP server cannot be resolved to an IP address. The machine in the DMZ only has its IP and default gateway configured, no DNS server.
Now, from Internal the DNS lookup seems to be handled by the ASG, where we have DNS servers configured under "Network Services" > DNS > Forwarders.
Question: how can I make this work for the DMZ interface as well?
Thanks in advance,
Klaus
