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.
