I am needing to test for open ports on specific IP addresses. I have one physical NIC with 4 IP's. One internal IP and 3 external facing IP's (Lync Edge 2013).
I need to be able to telnet to specific ports from specified IP addresses. How do I accomplish this? Please be detailed and specific please. I can view my routing table but Im not sure 100% at what I am looking at or perhaps need to change.
