And where should the devices route to? Enter the remote stations into the routing
table (configuration area 'IPX/SPX', 'Routing' tab) with an
internal network address
for the WAN (not that of another LAN). For the router in the network in the central
office the table appears as below:
cd /Setup/IPX-module/WAN-config/Routing-table
set Glasgow 00000101 802.3 Route Off
set London 00000102 802.3 Route Off
set Manchester 00000103 802.3 Route on
set Leeds 00000104 802.3 Route On
In addition to the device names of the router in the network at the remote station,
every entry in the routing table receives its own WAN address. Network address of
the WAN on which the binding '802.3' is used. Because, seen from the network in
the central office, there is a server for the remote stations in Manchester and Leeds,
the 'exponential backoff' mechanism is activated.
Further information on the function of the 'exponential backoff' mechanism is found in
'Exponential Backoff'.
The entry for the network in the Glasgow branch, for example, is as follows:
cd /Setup/IPX-module/WAN-config/Routing-table
set Example_Inc. 00000101 802.3 Route On
The network address of the WAN is the same as the entry for the branch network in
the router at the central office. '802.3' is always used as binding on the WAN.
Because from the point of view of the networks in the branches there is always a
server on the remote side, the 'exponential backoff' mechanism is activated here.
Remote access
The work of many employees in modern organizations depends less and less on any
definite location—the most important factor here is constant access to shared and freely
available information.
Remote access is the key to this. The router on the local network at the head office
enables colleagues to telecommute from their home offices and traveling staff to access
the office while on the road. The router naturally also does everything necessary to
protect the company's data during remote access: The callback function uses the names
and call numbers entered to give the open sesame to specified users only. And telephone
charges are calculated at head office, simplifying the billing process.
