15.3 Firewall Services

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. Use this
screen to prevent the ICMP response packet from being sent. This keeps outsiders from discovering your
Zyxel Device when unsupported ports are probed.
You can also use this screen to enable service blocking, enter/delete/modify the services you want to
block and the date/time you want to block them.
Click Configuration > Security > Firewall > Services. The screen appears as shown next.
