7.16 ICMP Screen
If an outside user attempts to probe an unsupported port on your LTE7460-M608, an Internet Control
Message Protocol (ICMP) response packet is automatically returned. This allows the outside user to know
the LTE7460-M608 exists. Your LTE7460-M608 supports anti-probing, which prevents the ICMP response
packet from being sent. This keeps outsiders from discovering your LTE7460-M608 when unsupported
ports are probed.
To change your LTE7460-M608’s security settings, click
Networking > ICMP
. The screen appears as shown.
Note: If you want your device to respond to pings and requests for unauthorized services, you
will also need to configure the firewall accordingly by disabling SPI.
