Configuring Upnp Port Mapping - ZyXEL Communications NSA221 User Manual

Chapter 8 Network
CIFS (Windows File Sharing)
Common Internet File System (CIFS) is a standard protocol supported by most
operating systems in order to share files across the network. Using UPnP port
mapping for CIFS allows users to connect from the Internet and use programs like
Windows Explorer to access the NSA's shares to copy files from the NSA, delete
files on the NSA, or upload files to the NSA from the Internet.
If you configure UPnP port mapping to allow CIFS access from the WAN but cannot
get it to work, you may also have to configure the Internet gateway to also allow
NetBIOS traffic. See
FTP
File Transfer Protocol is a standard file transfer service used on the Internet. Using
UPnP port mapping for FTP allows remote users to use FTP from the Internet to
access the NSA's shares. A user with read and write access to a share can copy
files from the share, delete files from the share, or upload files to the share. See
Section 9.4 on page 176
from the WAN, you may want to use a different WAN port number (instead of the
default of port 21) to make it more secure. Remember to tell the remote users to
use the custom port number when using FTP to access the NSA.
HTTP (Web Configurator)
You can use UPnP port mapping to allow access to the NSA's management
screens. If you use UPnP to allow web configurator access from the WAN, you may
want to use a different WAN port number (instead of the default of port 80) to
make it more secure. Remember to use the custom port number when accessing
the NSA's web configurator from the Internet.
HTTP (Web Published Shares)
This is the NSA's web publishing feature that lets people access files using a web
browser without having to log into the Home screens. Use UPnP port mapping to
allow access to these files from the Internet without having to enter a user name
or password. See
