Field Description
DoS Attack Threshold When the gateway suffers a continuous attack from
the Internet (Which is considered an abnormal con-
nection that makes many connection requests in a
limited time to consume or exhaust the memory of
the gateway.), the gateway will drop this traffic from
the attack sources instead of responding to them like
normal internet traffic. Please select your own thresh-
old bandwidth from the attack source on the Internet
by clicking the radio button (Normally when you
have less bandwidth to the Internet, you will have
a correspondingly smaller DoS Attack Threshold.)
Otherwise the DoS function will not work properly.
Block Request from WAN Port The block request from WAN port feature reinforces
your network security by hiding your network ports;
this makes it difficult for others to intrude onto your
network. This feature is enabled by default. However,
if you host servers on your LAN, you cannot enable
this feature since it will block users from the Internet
from reaching servers on your LAN.
Block Ping from WAN port This feature can prevent your network from being
“pinged”, or detected by other Internet users.
Block PPTP, L2TP, IPSec Request This feature blocks all VPN connection requests from
hosts outside your network.
Block UPnP Request from WAN Port This feature blocks all UPnP requests from hosts
outside your network.
