All,

I have a server that is running on my DMZ and I have noticed that it keeps making EPMAP connections to the DMZ Interface on the Firewall.

Why would this be?

EPMAP on 135 is used my MS Win Server and Exchange for a variety of processes.      Many are legit, but it is (or rwas) the entry point for a variety of Worms and malicious little apps.    

You definitely do not want to open that port to the public internet.      

Your DMZ server might be trying to contact the interface 'thinking' its a win server because of bad dns resolution or a hosts entry....   It must think that IP belongs to another win host.
