DoS
Denial of Service (DoS)
is a common packet attack, by transmitting a great amount of data or request
to your Internet IP address and server. The Internet connection will become very slow, and server may
stop responding because it is not capable to handle too much traffics. This router has a built-in DoS
attack prevention mechanism; when you activate it, the router will stop the DoS attack for you.

stop responding. Check this box and the router will filter this kind of
packet out.
Discard Ping from
WAN
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 router will ignore all inbound PING request, but when
you activate this function, you will not be able to ping your own router
from internet, too.
Port Scan
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 router will
block all traffics which are trying to scan your Internet IP address.
Sync Flood
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 router will filter this kind of
traffic out.
