Configuring Dierent Network Environments
Example: Internet connection of cameras with a DSL router
In this example, all of the cameras are connected via a DSL router with flat-rate Internet
access. You need a DynDNS name for the router, which you then enter together with the user
data in the router’s DynDNS client. Access to the individual cameras takes place by means of
port forwarding , in which the first camera, in our example, can be reached under the name
Fritz-Mueller.dyndns.org:19801, the second Fritz-Mueller.dyndns.
org:19802
, etc. (the numbers behind the colon are examples for the associated ports ).
Port forwarding is also set up in the router. Ports for the router’s external IP addresses (19801
and 19802 in the example) are connected with local (internal) IP addresses for cameras
(
192.168.178.201 and 192.168.178.202 in the example). In our example, both
ports are also linked with the IP addresses of the following cameras:
•
19801  192.168.178.201
• 19802  192.168.178.202
The router forwards a query to port 19801 at the external IP address 213.63.87.154
to the local IP address
192.168.178.201 and therefore to camera1 . Queries via the
external port 19802 are also forwarded to the local IP address 192.168.178.202 and
therefore to camera2 .

A port facilitates the
processing of different
services for a computer
over the same IP
address. This means
a computer can serve
simultaneously as a web
server (port
80) and as
a mail server (port
25
for sending, port
110
for receiving e-mails)
