Denial of service (DoS) prevention

Network > Firewall > DoS Prevention
The router supports prevention against common denial of service (DoS) attacks.
Malicious users use denial of service attacks to temporarily or permanently disrupt the
availability of services from network resource such as your router. Typically, DoS attacks
are achieved by flooding a specific network resource by excessively sending unnecessary
requests which can cause the network device or resource to stop functioning.
1. Log into your router management page (see
on page 8).
2. Click on Network, click on Firewall, and click on the DoS Prevention tab.
3. Review the settings below. When complete, Apply to save and commit your changes.
Choose the DoS prevention type to enable, TCP SYN flood, UDP flood, or ICMP flood.

DMZ Host

Network > Firewall > DMZ Host
You may want to expose a specific computer or device on your network to the Internet
to allow anyone to access it. Your router includes the DMZ (Demilitarized Zone) feature
that makes all the ports and services available on the WAN/Internet side of the router
and forwards all ports to a single IP address (computer or network device) on your
network. The DMZ feature is an easy way of allowing access from the Internet however,
it is a very insecure method and will open your local area network to greater threats
from Internet attacks. It is recommended to use
specific ports/services only.
1. Log into your router management page (see
on page 8).
2. Click on Network, click on Firewall, and click on the DMZ Host tab.
3. Review the settings below. When complete, Apply to save and commit your changes.

Enable – Check this option to enable DMZ host.

DMZ Host IP Address - Enter the IP address you assigned to the computer or
network device to expose to the Internet. (e.g. 192.168.10.250)
