Services Screen

If an outside user attempts to probe an unsupported port on your MWR211, an
ICMP response packet is automatically returned. This allows the outside user to
know the MWR211 exists. Use this screen to prevent the ICMP response packet
from being sent. This keeps outsiders from discovering your MWR211 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 Security > Firewall > Services. The screen appears as shown next.
