Discard Ping
Ping is a common and useful tool to know
From WAN (2):
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 packets, to make your Internet connection
become very slow, even unusable. Check this box
and the router will ignore all inbound PING
requests, but when you activate this function, you
will not be able to ping your own router from the
Internet, too.
Port Scan (3):
Some malicious intruders 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 router will block all traffics that are trying
to scan your Internet IP address.
Sync Flood (4):
This is another kind of attack, which uses a lot of
fake connection request to consume the memory of
your server, and tries to make your server become
unusable. Check this box and the router will filter
this kind of traffic out.
