A consultant will be installing an agent in some of our internal servers so they can monitor them from the outside. This agent needs to talk to an specific IP as well as Port on the outside interface and the communication is bidirectional. I don't have enough outside IPs to do a one to one translation so I am reaching out to you to see what is the best way to accomplish this.
This is what I would do:
1. Create an object group with all the servers
2. Create an access list with the above object group to allow the agent access to the specified IP and port #
3. Deny statement to block the rest of the traffic
May I hear your suggestions?
