Chapter 22 Remote Management
132
If an outside user attempts to probe an unsupported port on your Router, an ICMP response packet
is automatically returned. This allows the outside user to know the Router exists. Your Router
supports anti-probing, which prevents the ICMP response packet from being sent. This keeps
outsiders from discovering your Router when unsupported ports are probed.

encryption to provide secure encrypted communication between two hosts over an unsecured
network. The following file transfer methods use SSH:
•
