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 

 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.
