Gateway and routing
If data must be sent beyond the limits of a local network to a destination in another
segment (different network code), a Gateway (GW) must be defined via a gateway ad-
dress, which is located within the local network segment. A gateway is a device with two
network interfaces which acts as an exchange station between the network segments.
If a device detects that the destination address is not located in the own, local segment
(comparison of the own IP with the destination IP via NM), the packet is instead sent to
the GW. The GW will route the packet accordingly, i.e. will send it to the second network
segment connected to the GW.
The network settings of a PC can easily be queried using the command 'ipconfig' in the
DOS box:
More information regarding the topics IP addresses and routing can be found at
http://en.wikipedia.org/ Search for the term 'ip address'.
Note
When the parameters are automatically allocated via DHCP, an ac-
tive DHCP server with an appropriate configuration must be avail-
able in the network. The DHCP server allocates the IP address to the
INSYS Ethernet automatically after each restart.
Warning!
In the case of manual parameter allocation, the selected address, Net-
mask and the gateway must match the local network segment, in
which the INSYS Ethernet is located. An IP address that already exists in
the network may not be re-allocated!
When integrating the INSYS Ethernet into a company network, the re-
sponsible network administrator must be consulted. It manages the IP
addresses or configures the DHCP server, if required.
