15.3 Services Screen
If an outside user attempts to probe an unsupported port on your EMG2926-Q10A, an ICMP
response packet is automatically returned. This allows the outside user to know the EMG2926-Q10A
exists. Use this screen to prevent the ICMP response packet from being sent. This keeps outsiders
from discovering your EMG2926-Q10A when unsupported ports are probed.
You can also use this screen to enable/add/delete/modify an IPv4 firewall rule.
