DHCP The DHCP server automatically
assigns the IP address, subnet mask,
gateway and name server to a network
device.
DHCPs are available in current
routers. The DHCP service must be
specially set and activated (see the
relevant manual for more information).
Note:
When using fixed IP addresses
together with a DHCP server, you
should ensure that the fixed IP
addresses are outside of the
addresses assigned by DHCP to avoid
problems occurring.
Port A port is an interface that enables
different programs to communicate.
Certain ports are fixed (23: Telnet, 21:
FTP), whilst others can be freely
selected. Ports are relevant for various
applications, e.g. for external access
to the device via a browser.
MAC address The MAC address (Media Access
Control address or Ethernet ID) is the
specific hardware address of the
network adapter.
It is used for the unique identification
of the device on a computer network.
Network layout
The device must be physically connected to the network
with a CAT5 cable; see Connections on page 75
Note
Please follow the instructions and notes for the
network devices.
Several switches/routers/access points can be connected
to one another. Firewalls and other security software may
have a negative effect on the network.
Warning
When using a router, the network clients, and
therefore the recorder, are "connected" to the
internet and vice versa.
You should make sure that you take protective
measures, such as using a firewall, changing your
password and changing the port, to prevent
unauthorised external access.
