Manual Setup Step 2: Configuring your Router to allow
Remote Access
If your camera was automatically set up with UPnP you would skip this section
and proceed directly to Step 3: Choosing a name for your camera.
If you have only 1 camera, it is simplest to configure your router to use “DMZ”
for the camera. This basically means that any request from the internet is
forwarded to your single camera. However many of our customers use more
than one camera so we will explain the port forwarding procedure.
Port forwarding is sometimes called “virtual server”, “user defined service”, or
“port mapping” and is explained in your router’s manual or online help. The
manual is usually available from the manufacturer’s tech support web site.
Typically you need to provide a “service name” for each group of ports that is
forwarded. The name could be anything that isn’t already used, for example
“Cam1HTTP” and “Cam1RTP”. Then you typically need to enter the external
(public) and internal (host) ports and select either TCP or UDP. For browser
access to the camera you need to forward public TCP port 8150 to internal
port (base port) 80. If you have an older LinkSys it may not have a distinction
between public and private port. Then you’d have to change your camera’s
HTTP port to 8150 in the TCP/IP menu (shown on previous page), and then use
that port even for local access (for example
http://192.168.0.101:8150
)
For cell phone access (RTP) you also need to forward UDP ports 30000 and
30001, however this time the external and internal ports are both the same.
Your 2
nd
camera would use TCP port 8151 and UDP ports 30002-30003, the 3
rd
camera would use TCP port 8152 and UDP ports 30004 – 30005 etc.
After these settings, your router typically needs to be restarted and then
you’re ready to use the camera over the internet. First you need your router’s
IP address on the internet (that’s NOT the local address that starts with
192.168). You can find this address by looking at your router’s WAN menu, or
you can use
www.checkip.org
A friend who is outside your local network should then be able to access your
camera using this IP address and port 8150, as in
http://123.45.67.89:8150
