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 cable modem
router to respond to a ping to its WAN (Internet) port.
To view the WAN settings:
1.
Launch a web browser from a computer or mobile device that is connected to your Orbi network.
2.
Enter orbilogin.com.
A login window opens.
3.
Enter the admin user name and password.
The user name is admin. The password is the one that you specified the first time that you logged in.
The user name and password are case-sensitive.
The BASIC Home page displays.
4.
Select ADVANCED > Setup > WAN Setup
The WAN Setup page displays.

View or change the following settings:
•
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 42.
•
Respond to Ping on Internet Port. This feature allows your cable modem 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, 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 ?.
•
NAT Filtering. Network Address Translation (NAT) determines how the cable modem 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.
