You can view or configure wide area network (WAN) settings for the Internet port. You can set up a DMZ (demilitarized zone) server, change the maximum transmit unit (MTU) size, and enable the router to respond to a ping to its WAN (Internet) port.
To view the WAN settings:
1. Launch an Internet browser from a computer or wireless device that is connected to the network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login screen displays.
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 screen displays.
4. Select ADVANCED > Setup > WAN Setup.
The following settings display:
-
Disable Port Scan and DoS Protection. DoS protection protects your LAN against denial of service attacks such as Syn flood, Smurf Attack, Ping of Death, and many others. Select this check box only in special circumstances.
-
Default DMZ Server. This feature is sometimes helpful when you are playing online games or videoconferencing, but it makes the firewall security less effective. See Set Up a Default DMZ Server on page 96.
-
Respond to Ping on Internet Port. This feature allows your router to be discovered. Use this feature only as a diagnostic tool or if you have a specific reason.
-
Disable IGMP Proxying. IGMP proxying allows a computer on the local area network (LAN) to receive the multicast traffic it is interested in from the Internet. If you do not need this feature, you can select this check box to disable it.
-
MTU Size (in bytes). The normal MTU (maximum transmit unit) value for most Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. Change the MTU only if you are sure that it is necessary for your ISP connection. See Change the MTU Size on page 35.
-
NAT Filtering. Network Address Translation (NAT) determines how the router 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.
