Do not respond to

Select this to prevent outsiders from discovering your ZyXEL Device by sending

requests for

requests to unsupported port numbers. If an outside user attempts to probe an

unauthorized

unsupported port on your ZyXEL Device, an ICMP response packet is

services

automatically returned. This allows the outside user to know the ZyXEL Device

 

exists. Your ZyXEL Device supports anti-probing, which prevents the ICMP

 

response packet from being sent. This keeps outsiders from discovering your

 

ZyXEL Device when unsupported ports are probed.

 

If you clear this, your ZyXEL Device replies with an ICMP Port Unreachable packet

 

for a port probe on unused UDP ports and with a TCP Reset packet for a port

 

probe on unused TCP ports.
