The 2M-C3W includes support for UPnP™. UPnP™ is enabled by default, and the 2M-C3W then is
automatically detected by operating systems and clients that support this protocol.
Note:
UPnP™ must be installed on your workstation if running Windows XP. To do this, open the
Control Panel from the Start Menu and select Add/Remove Programs. Select Add/Remove Windows
Components and open the Networking Services section. Click Details and then select UPnP™ as the
service to add.
NAT Traversal
A broadband router allows devices on a private network (LAN) to share a single connection to the
Internet. This is done by forwarding network traffic from the private network to the “outside”, that is,
the Internet. Security on the private network (LAN) is increased since most broadband routers are
pre-configured to stop attempts to access the private network (LAN) from the public network/Internet.
Use
NAT traversal
when your 2M-C3Ws are located on an intranet (LAN) and you wish to make it
available from the other (WAN) side of a NAT router. With NAT traversal properly configured, all HTTP
traffic to an external HTTP port in the NAT router is forwarded to the 2M-C3W.
Notes:
-
For NAT traversal to work, this must be supported by the broadband router.
-
The broadband router has many different names:
“NAT router”, “Network router“, Internet Gateway”, “Broadband sharing device” or “Home
firewall” but the essential purpose of the device is the same.
