LABEL

DESCRIPTION

LAN

Use these fields to specify what port the Internet gateway uses to connect from its LAN

 

port to the service on the NSA.

 

 

Service Name

This read-only field identifies a service on the NSA.

 

 

LAN Port

Specify the port number (1~65,536) the Internet gateway needs to use to connect from

 

its LAN port to the service on the NSA. This is the NSA’s internal port number for the

 

service. Changing a service’s port number in this screen also changes it in other NSA

 

screens that display it. Similarly, changing a service’s port number in another NSA screen

 

also changes it here.

 

 

 

The number below this icon is your Internet gateway’s WAN IP address (the IP address

 

your Internet gateway uses for connecting to the Internet).

 

 

WAN

Use these fields to specify what port Internet users must use to connect to the Internet

 

gateway’s WAN port in order to connect to the service on the NSA.

 

 

Service Name

This read-only field identifies a service on the NSA.

 

 

Enable WAN

Select this check box to have UPnP configure your Internet gateway to allow access from

Access

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.

 

P2P download’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.

 

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.

 

 

Reset

Click Reset to begin configuring this screen afresh.
