3. Select ADVANCED > Setup > WAN Setup. The WAN Setup page displays.
View or change the following settings:
• DisablePortScanandDoSProtection. 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.
• 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.
• 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.
• 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.
• 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.
4. 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.
