8.6 The PPPoE Screen
Use this screen to configure PPPoE settings for a direct Internet connection.
Enable WAN
Access
Select this check box to have UPnP configure your Internet gateway to
allow access from the Internet to the NSA’s service.
If you clear this check box, people will not be able to access the NSA’s
service from the Internet unless you manually configure the Internet
gateway’s firewall and NAT rules to allow access.
WAN Port When you enable WAN access for one of the NSA’s services, specify the
port number (1~65,536) Internet uses need to use to connect to the
Internet gateway’s WAN port in order to access the service on the NSA.
Whoever wants to access a service on the NSA from the Internet must
use this port number.
BitTorrent’s WAN port must be the same as the LAN port.
Make sure there is not another service using TCP protocol with the same
port number. See Appendix C on page 407 for a list of common services
and their associated protocols and port numbers.
If another device is using the same port (the Internet gateway has the
same port number mapped to another LAN IP address), the NSA
overwrites it when you apply the setting and WAN users can no longer
access the other device.
This icon means the service’s LAN and WAN port numbers must be the
same.
This icon means another service is using the same port number as this
service. Change the port number of one of the services so they use
different port numbers.
This icon means another service is using the listed port, but the port the
other service is using will be replaced if you apply the setting. The other
service will no longer be accessible from the listed port.
Apply Click Apply to save your changes back to the NSA.
