How Do I Configure the Wireless Home Gateway?
Setup Advanced Settings - Port Triggers Page Description
Use this page to enter and enable the port forwarding trigger and target range start
and end ports along with protocol information in the appropriate fields. The
following example illustrates how to use the port triggering feature to configure the
Microsoft X-Box Online Live for Internet gaming.
Note: For most widely used applications (including Microsoft X-Box Online Live),
the built-in firewall automatically maps and opens ports required for that
application while the application is in use.
1. In the first row, enter 88 in both Start Port and End Port fields.
2. In the same row, select UDP from the drop-down list in the
Protocol field, and then select the box in the Enable field.
3. In the second row, enter 3074 in both Start Port and End Port fields.
4. In the same row as the second entry, select Both, and then select the
box in the Enable field.
5. Click Apply to apply and save your new port forwarding settings.
Configuring the DMZ Host
Use the Setup Advanced Settings - DMZ Host page to configure an IP address that is
visible to the WAN. DMZ hosting is commonly referred to as "exposed host," and
allows you to specify the "default" recipient of WAN traffic that Network Address
Translation (NAT) is unable to translate to a known local PC. DMZ allows one IP
address to be unprotected while others remain protected.
Note: If you are not familiar with the advanced settings detailed in this section,
contact your service provider before you attempt to change any of the wireless home
gateway default advanced DMZ host settings.
Click DMZ Host in the Advanced Settings section of the Setup page to access the
Setup Advanced Settings - DMZ Host page.
