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 modem to respond to a ping to its WAN (Internet) port. This feature allows your
modem 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 that is connected to the network.
2.
Enter http://www.routerlogin.net.
A login window opens.
3.
Enter the modem 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, clear the Disable Port Scan and DoS Protection
check box.
6.
To enable the modem to respond to a ping, select the Respond to Ping on Internet Port check box.
7.
Click the Apply button.
Your settings are saved.
Manage NAT Filtering
Network Address Translation (NAT) determines how the modem processes inbound traffic. Secured NAT
protects computers on the LAN from attacks from the Internet but might prevent some Internet games,
point-to-point applications, or multimedia applications from working. Open NAT provides a much less secured
firewall but allows almost all Internet applications to work. Secured NAT is the default setting.
To change the default NAT filtering settings:
1.
Launch a web browser from a computer that is connected to the network.
2.
Enter http://www.routerlogin.net.
A login window opens.
3.
Enter the modem 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.
