Parameters Description
Administrator Time-out The system will log out the administrator after no activity for a
period of time. You may set the time-out period to zero to disable
this feature.
Remote Administrator Host: Port
This feature enables you to perform administration task from
remote host. If this feature is enabled, only the specified IP
address can perform remote administration. Setting the specified
IP address as 0.0.0.0 indicates any host can connect with this
product to perform administration task. You can use subnet mask
bits "/nn" notation to specified a group of trusted IP addresses, for
example, "10.1.2.0/24".
NOTE: When Remote Administration is enabled, port 80 will be
opened; you can change to other port number such as 8080.
Discard PING from WAN side
Check this box to enable Discard PING from WAN side. When
you enable this feature, your router will not respond to a “ping”
request from any host on the WAN side.
DoS Attack Detection
Check this box to enable the DoS Attack Detection. Router will
block the DoS once it is detected. Denial of Service (DoS) is a
common attack measure, 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.
