Do not respond
to requests for
unauthorized
services
Select this to prevent outsiders from discovering your WiMAX Modem by
sending requests to unsupported port numbers. If an outside user
attempts to probe an unsupported port on your WiMAX Modem, an
ICMP response packet is automatically returned. This allows the outside
user to know the WiMAX Modem exists. Your WiMAX Modem supports
anti-probing, which prevents the ICMP response packet from being
sent. This keeps outsiders from discovering your WiMAX Modem when
unsupported ports are probed.
If you clear this, your WiMAX Modem replies with an ICMP Port
Unreachable packet for a port probe on unused UDP ports and with a
TCP Reset packet for a port probe on unused TCP ports.
