Chapter 8 Network
Table 30 Network > UPnP > Port Mapping (continued)
LABEL | 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. |
|
|
Apply | Click Apply to save your changes back to the NSA. |
