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.
