11.4 Services Screen
Click Security > Firewall > Services. The screen appears as shown next.
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.
