3.5.3 Denial of Service (DoS)

The XRT-412's firewall can block common hacker attacks, including Denial of Service, Ping of Death, Port Scan and Sync Flood. If Internet attacks occur the router can log the events.

Parameters

Description

Ping of Death

Protections from Ping of Death attack

Discard Ping From WAN

The router’s WAN port will not respond to any

 

Ping requests

Port Scan

Protection the router from Port Scan.

Sync Flood

Protection the router from Sync Flood attack.

If you want to define the content of DoS by yourself, you can select “Advance Settings” and configure the setting based on your request.

When all setting is done, click <Apply> at the bottom of the screen to save the above configurations. You can now configure other advance sections or start using the router (with the advance settings in place).

3.5.4 DMZ

If you have a local client PC that cannot run an Internet application (e.g. Games) properly from behind the NAT firewall, then you can open the client up to unrestricted two-way Internet access by defining a DMZ Host. The DMZ function allows you to re-direct all packets going to your WAN port IP address to a particular IP address in your LAN. The difference between the virtual server and the DMZ function is that the virtual server re-directs a particular service/Internet application (e.g. FTP, websites) to a particular LAN client/server, whereas DMZ re-directs all packets (regardless of services) going to your WAN IP address to a particular LAN client/server.
