ICMP
. The screen
appears as shown.
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.
