Point-to-Point Protocol (PPP)
4-12 893-826-A
To gain access to a remote subnet, a device on the LAN must use the
communication server as a router or send network traffic to a router on the
LAN, if one exists, which can then send the traffic to the communication server.
Most UNIX hosts support a ROUTE ADD HOST command, which identifies
devices that act as routers to a remote subnet.
In Figure 4-4, for example, you can define Server B (140.179.41.25) as the
router for UNIX Host B to use when it attempts to gain access to UNIX Host A
(140.180.5.38) on LAN A. You can also define Router B (140.179.40.28) as the
default router to use when UNIX Host B attempts to reach a device on LAN A
(140.180.0.0).
Configuring IPXCP Connections
After the port has been configured for PPP operation, you must configure
IPXCP characteristics. This procedure requires three tasks:
• Specify SERVER characteristics.
• Specify PORT characteristics.
• Configure IPX clients with the client software.
You can also refer to the documentation supplied with the IPX client software
package for more information about configuring IPXCP connections.
The communication server can communicate with any RFC 1552-compliant
IPXCP (IPX over PPP) client software implementation (a version of the
Stampede Remote Office client software, for example). Using this software,
users at the remote IPX clients, such as remote (dial-in) workstations or PCs,
have access to the Novell services offered on the Novell Netware network
(unless the network manager chooses to limit that access). Users dial in when
they need access to the services and disconnect when the services are no longer
needed. This application is a typical “remote office” or “user-to-LAN”
application.
• Optionally, configure a unit to use static IPX RIP routes or SAP services.
• Optionally, configure a unit to use IPX routing or filtering. (This task is
covered later in this chapter.)
Specify IPXCP-Related SERVER characteristics
You must specify a number of SERVER characteristics that allow the server to
operate as an IPX node on the Ethernet network. The following is a summary of
these SERVER characteristics. Refer to Model 3395/3395A Commands
Reference for more information about these commands.
NOTE: In order for the changes, specified by the DEFINE SERVER
commands listed below, to take effect, you must reinitialize the server after
issuing the commands.
