Question
Is it possible to use Monitor Solution in a DMZ environment?

Can I monitor servers that are located behind a DMZ?

Answer
As long as all appropriate communication can take place between the Notification Server and the target machine, you can monitor servers that are located in a DMZ.

Ensure that the following communication can take place:

TCP Port 80 (2-way) to all target servers for Altiris Agent to Notification Server communication

TCP Port 1011 (2-way) to all target servers for Monitor Solution's Performance Monitor to Monitor Agent communication

Proper name resolution for all target servers from the Notification Server

If the servers in the DMZ are members of a different domain than the Notification Server, the trusts between both domains must be properly configured
