Note: The NSA does not use any security for the files in the published folders. It is not
recommended to publish shares if you do not have the NSA behind a good
hardware-based firewall. See
Additionally, you can use HTML editing software (not included) to create an
index.html or index.htm file to define and customize how your website works and
looks.
Accessing Web-published Shares from the Internet
You need to use a public address to access the NSA's web-published shares from
the Internet. If your NSA uses a private IP address, you may need to use the
public IP address of your Internet gateway and configure NAT or port forwarding
on your Internet gateway and possibly firewall rules in order to let people access
the NSA's web-published shares from the Internet.
Web Publishing Port Number
If the web-published shares use a port number other than 80 (the normal port for
web traffic), users must include it after the NSA's IP address in order to access the
NSA's web-published shares. For example, say you specified port 8080, the NSA's
IP address is 192.168.1.23, and the name of the web-published share is
FamilyPhotos. You would have to enter "http://192.168.1.23:8080/MyWeb/
FamilyPhotos/" in your browser's address bar to access the share's web page.
The NSA's web configurator uses port 80. To make the web configurator more
secure, you can have the web-published shares use another port number. Then
you can configure one set of firewall rules and NAT or port forwarding settings on
your Internet gateway specifically for allowing access to the web-published shares
and another separate set of rules for accessing the NSA's web configurator.
