Advanced > NAT > Port Forwarding

Note:

This option is not available if your NB9/NB9W is in Bridge mode.

To display the NAT function, you need to have enabled the NAT feature in the WAN Setup. By

default, NAT is enabled on your NB9/NB9W

Clicking on Advanced > NAT displays the following:

The Port Forwarding feature allows you to direct incoming trafﬁc from WAN side (identiﬁed by

Protocol and External port) to the Internal server with private IP address on the LAN side. The

Internal port is required only if the external port needs to be converted to a different port number

used by the server on the LAN side. A maximum of 32 entries can be conﬁgured.

For example, you may want to setup an FTP server with IP address 192.168.1.110 on your LAN for

people to connect to. The default port that an FTP server listens on is port 21. So, to this set this up

you would do the following:

Click on 'Add' .

If you are setting up a common server (e.g FTP) you can select the type of server from the

dropdown list. Selecting the server will automatically conﬁgure the necessary ports:

Enter the Server's IP address (e.g. 192.168.1.110)

Click 'Save / Apply'
