16.7 The ICMP Screen
To change your ZyXEL Device’s security settings, click
Advanced > Remote MGMT

ICMP
. The
screen appears as shown.
If an outside user attempts to probe an unsupported port on your ZyXEL Device, an ICMP response
packet is 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.
Note: If you want your device to respond to pings and requests for unauthorized services,
you may also need to configure the firewall anti probing settings to match.
