Manage the WAN Security Settings
The WAN security settings include port scan protection and denial of service (DoS) protection, which can protect
your LAN against attacks such as Syn flood, Smurf Attack, Ping of Death, and many others. By default, DoS protection
is enabled and a port scan is rejected.
You can also enable the router to respond to a ping to its WAN (Internet) port. This feature allows your router to be
discovered. Enable this feature only as a diagnostic tool or if a specific reason exists.
To change the default WAN security settings:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
2.
Enter http://www.routerlogin.net.
A login window opens.
3.
Enter the router user name and password.
The user name is admin. The default password is password. The user name and password are case-sensitive.
The BASIC Home page displays.
4.
Select ADVANCED > Setup > WAN Setup.
The WAN Setup page displays.
5.
To enable a port scan and disable DoS protection, select the Disable Port Scan and DoS Protection check
box.
6.
To enable the router to respond to a ping, select the Respond to Ping on Internet Port check box.
7.
Click the Apply button.
Your settings are saved.
Set Up a Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and videoconferencing applications
that are incompatible with Network Address Translation (NAT). The router is programmed to recognize some of
these applications and to work correctly with them, but other applications might not function well. In some cases,
one local computer can run the application correctly if the IP address for that computer is entered as the default
DMZ server.
WARNING:
DMZ servers pose a security risk. A computer designated as the default DMZ server
loses much of the protection of the firewall and is exposed to exploits from the
Internet. If compromised, the DMZ server computer can be used to attack other
computers on your network.
