Adding Internet router to NMS through a firewall

Hi,

I need to add my Internet facing router to my NMS server which is in the DMZ behind an ASA(diagram attached). What is the most secure way to acheive my goal?

BR,

Raheel

Hi Raheel,

For the ASA role, you can make a very specific access-list only permitting this traffic through.   Who will initiate the traffic, the NMS device?  If so, then you will be going from a more secure (DMZ)  to less secure network (outside).  So your access-list would permit only the NMS talking with the outside router on a specific port that you use to manage the router.

thanks,

scott
