DESCRIPTION
Select the interface(s) on which the WiMAX Device should respond to
incoming ping requests.
• Disable - the WiMAX Device does not respond to any ping requests.
• LAN - the WiMAX Device only responds to ping requests received
from the LAN.
• WAN - the WiMAX Device only responds to ping requests received
from the WAN.
• LAN & WAN - the WiMAX Device responds to ping requests received
from the LAN or the WAN.
Select this to prevent outsiders from discovering your WiMAX Device by
sending requests to unsupported port numbers. If an outside user
attempts to probe an unsupported port on your WiMAX Device, an ICMP
response packet is automatically returned. This allows the outside user
to know the WiMAX Device exists. Your WiMAX Device supports anti-
probing, which prevents the ICMP response packet from being sent.
This keeps outsiders from discovering your WiMAX Device when
unsupported ports are probed.
If you clear this, your WiMAX Device 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.
