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.
