IPX Setup
The IPX Virtual Port Setup dialog box is used to control the four frame types and set up the three
WAN ports of the RASFinder. The Advanced tab opens an IPX general setup window used to enable
or disable IPX routing and autolearn of Ethernet network numbers; also, the distributed name of the
RASFinder can be designated here.
In IPX based networks using Ethernet, LAN segments can support the use of four different Ethernet
frame formats over the same physical link (provided each frame type has a unique network address
as a virtual port).
The three WAN tabs allow you to enable or disable IPX routing on the WAN ports, change the
network numbers for the WAN ports, change the default RIP and SAP timers, and optimize the
bandwidth. The IPX WAN network number has to be the same on both ends of the link and must be
unique throughout the internetwork. If a WAN port is configured in a point-to-point operation, both
WAN network numbers have to be the same and unique.
NetBIOS, when enabled, enables the transport of Novell encapsulated NetBIOS packets on the
specified virtual IPX port. Refer to Novell documentation regarding NetBIOS operation over NetWare
based LANs. The Hops text box defines the distance, in hops, for the routing of Novell encapsulated
NetBIOS frames on the specified virtual IPX port, and the recommended value is 8.
Periodic RIP (Routing Information Protocol) refers to broadcasts transmitted from the RIP virtual IPX
port at a given frequency so all routers on the internetwork maintain consistent routing tables.
Increasing the frequency of RIP broadcasts can consume excessive bandwidth, especially on low-
speed WAN links. Sixty seconds is the recommended interval between RIP broadcasts. The default
RIP timer settings should work well for most applications.
Periodic SAP (Service Advertisement Protocol) is used in IPX based networks to enable servers
(application servers, file servers, print servers, communication servers, etc.) to advertise their
presence on the internetwork. Routers use these advertisements to build up tables listing the servers
so they can then advertise these servers on the local segments and provide routers to the server.
Client workstations can request a list of these servers from the router. The default SAP timer settings
should work well for most applications.
