If no connection or channel is available, the packet is discarded. As a result, the
maximum number of remote stations that can receive propagated frames
corresponds to the number of possible simultaneous connections. The default
setting is 'Filter'.
Backoff: The IPX router uses a special algorithm (exponential backoff) to keep the
connection charges as low as possible in the event of erroneous configurations (see
below).
If there is no server in the remote network (e.g. with remote access from a
workstation), the router cannot detect this and the corresponding remote station
will be deactivated after a day at the latest. In order to prevent this from happening,
the exponential backoff algorithm can be deactivated for these remote stations.
The default setting is 'On'.
Socket-filter The socket filter table permits the selective filtering of WAN packets to specific ranges
of destination sockets. Filtering is performed for both single IPX packets and propagated
IPX packets.
Setup/IPX-module/RIP-configuration
This option allows you to store settings for RIP data packets (router information). The
menu has the following layout:
/RIP-configuration
Table-RIP
LAN-filter-table
WAN-filter-table
Routes/Frm
Aging-minute(s)
Spoofing
WAN-update-min.
Table-RIP This option allows you to display the entries in the current RIP table. The table contains
a maximum of 256 entries.
The entries in the RIP table might, for example, look like the entries shown below with
the networks 00000001, 00000002, 00000010, 00000081, where these networks can be
accessed via different routers. The flags can be used to determine where these networks
are located with relation to the particular router (local or remote). The entry direct
indicates whether this network is directly the local or remote network. DOWN indicates
