View or Change WAN Settings
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 or change the WAN settings:
1.
Launch a web browser from a computer or mobile device that is connected to the network.
2.
Type 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.
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
on page 50.
•
Respond to Ping on Internet Port. This feature allows your router to be discovered. Use this
feature only as a diagnostic tool or for 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
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.
•
Disable SIP ALG. Some voice and video communication applications do not work well with the SIP
ALG. Disabling the SIP ALG might help your voice and video applications to create and accept a
call through the router.
