A.1.3 Router
A router is normally used to establish a connection to the Internet. Technically speak-
ing, a router transfers requests to external IP addresses of computers that are located
outside of the local network. If a router has a sufficient number of network ports, it can
also function as a switch.
A router performs these functions, among others, for the units joined in the network:
•
DHCP:
Using this function, individual network devices in the local network (cameras
and computers) are automatically assigned unique IP addresses to enable com-
munication between these units.
•
Internet Connection:
The router establishes a connection to an Internet service pro-
vider (ISP) and receives a unique public IP address (an address that is recognized and
available online). Requests sent to an external IP address (e.g. a website) are sent
to this public address via the router and the results are sent back to the requesting
computer. Normally, a permanent connection to the provider is established.
•
DynDNS:
Each time the Internet connection is reestablished, the ISP automatically
assigns the router a different public IP address (for example, if the provider interrupts
the connection overnight). In order to assign a unique, static name to these constantly
changing IP addresses, register with a free DynDNS provider (for example,
www.
dyndns.org
) and create a name for your router and Internet connection (for
example,
myhomenetwork.dyndns.org
).
This unique name (for example, myhomenetwork.dyndns.org ) is entered into
the router along with the registration information of the DynDNS provider (user name
and password). Each time the router’s public IP address is reset by the provider, the
router registers this IP address with the DynDNS provider where the address is then
linked to your unique name.
•
Port Forwarding:
It is possible to access individual network devices (for example,
cameras) from outside the network using this router feature. A camera is assigned
to a port in the router. This port sends information to the internal network address
of the camera. In conjunction with DynDNS, you can access your first camera using
mycamera.dyndns.org: 19801
as address. MxEasy configures the connected
cameras automatically so that each camera can be used from outside the network
as a proxy camera.
For more information on these services, see the section Directly Accessing MOBOTIX
Cameras via the Web in the Software Manual. Section 3.1.3, “Adding Remote Cameras
Using DynDNS”, contains more information on the
DynDNS
and
port forwarding
topics.
