SPX-watch This option allows you to define the type of management used for SPX watchdog packets.
쮿
Route causes the SPX watchdog packets to be transferred and, consequently, also
causes a regular establishment of connections by means of the server’s SPX
watchdog packets.
쮿
Spoof (default) causes SPX watchdog packets to be answered locally. This setting
is especially economical.
NetBIOS-watch This item specifies how NetBIOS watchdog packets should be treated. NetBIOS
watchdog packets occur, e.g., if Windows networks are connected by IPX. The same
options are available as with IPX or SPX watchdog packets (filter, route, spoof).
Socket-filter The socket filter table permits the selective filtering of LAN packets to specific ranges of
destination sockets. Filtering is performed for both single IPX packets and propagated
IPX packets. The following sockets (which are periodically sent in the network and,
therefore, would result in connections being established too frequently) are already
entered in the LAN filter table as default values (for details, also see FAQs on the
'IPX router').
Loc.-routing This setting supports the scaling of multiple routers in a local network. When all the
channels for one router are already seized and packets for other remote stations are still
being received at this router, other routers in the LAN may still have free channels.
If the 'Loc.-routing' option is activated, the router forwards the packets in the local
network to a router that has propagated a route to the remote station desired. The router
has saved this route, although it is less efficient than its own, and marked it with the
'reserve' flag in the RIP table.
The default setting for this option is 'Off' since an IPX client sends a RIP request for the
relevant route after a timeout, thus automatically finding a different router through which
it can access the destination network.
RIP-SAP-scal. Another option for supporting scaling is to propagate every route to which there is an
active connection with a somewhat better tic count than the actual one. This will ensure
that all clients will send their packets for these routes to the router that has the
connection. In addition, in the event that all channels are busy, the routes that are no
longer available will be propagated as 'DOWN'. Because one or more broadcasts are
