and is assigned this address by the remote station. Use this setting when the
remote station (e.g. your Internet provider) has assigned you a fixed IP address in the
access data. Of course, this procedure will only function when this address has also
been entered in the router as the IP address.
The IP routing table is generally sorted as shown below:
The longest network mask is placed on top.
For network masks of equal length, the one with the smallest IP address is placed
on top.
In order to identify the correct remote station, the router searches the routing table from
top to bottom using the destination IP address received. If a matching entry is found, the
router name found is used for establishing the connection.
Address ranges that are prohibited in the Internet are excluded from transmission by
preset entries in the IP routing table (the router name 0.0.0.0 means that packets to these
addresses are not transmitted). The IP routing table below is provided by way of example
and also shows the default settings:
IP-address
192.168.0.0
172.16.0.0
10.0.0.0
224.0.0.0
However, if these addresses are required for Intranet use, for example, it is possible to
delete the predefined entries at any time. If the routing table contains no entries with
the router name 0.0.0.0, the router processes all IP addresses with valid routes.
Example
– The local network address is 192.120.130.0.
– Three terminal units must be available via proxy ARP with the IP addresses
– Two destination networks 192.120.131.0 and 192.120.132.0 can be accessed by
– Data packets for the destination network 193.140.300.0 are to be sent to another
– Absolutely nothing is to be transmitted to the destination network
– All other non-local data packets must be sent to the router 'PROVIDER' at the
