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
K
– The local network address is 192.120.130.0.
– 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
In this example, the router table would contain the following entries:
IP-address
193.140.200.0
193.140.300.0
255.255.255.255
The last line is an entry for the "default route". The IP address 255.255.255.255
means the same as 0.0.0.0 (for technical reasons, 0.0.0.0 cannot be entered in the
first column). Because it contains the IP network mask 0.0.0.0, this line is always
appropriate after the rest of the table has been searched. Therefore, the router
sends everything that it cannot transfer over other routes and should not discard or
that comes from a WAN terminal and is not local to the router at the provider.
This table allows you to filter specific ranges of destination ports. In addition, you can
LAN-filter-table
determine how the packets are to be filtered. If packets with the entered ports are
received from the LAN side, they will not be forwarded (always filter) unless a connection
is currently in place (connect filter) or unless they can be routed over other than the
DEFAULT route (I-Net filter).
