Ping is a common and useful tool to know
the connection status of a specified remote network device, but
some malicious intruder will try to fill your network bandwidth
with a lot of PING request data packet, to make your internet
connection become very slow, even unusable. Check this box
and the Smart Repeater Pro will ignore all inbound PING
request, but when you activate this function, you will not be able
to ping your own Smart Repeater Pro from internet, too.
Some malicious intruder will try to use a 'port scanner' to know
how many ports of your Internet IP address are open, and they
can collect a lot of valuable information by doing so. Check this
box and the Smart Repeater Pro will block all traffics which are
trying to scan your Internet IP address.
This is another kind of attack, which uses a lot of fake
connection request to consume the memory of your server, and
try to make your server become unusable. Check this box and
the Smart Repeater Pro will filter this kind of traffic out.
