DESCRIPTION

Enable WAN

Select this check box to have UPnP configure your Internet gateway to

Access

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.
