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 RouteFinder. The Advanced tab controls the routing of the protocol and auto
learn of Ethernet network numbers, defines the broadcast name of the RouteFinder, and IPX
filtering.
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).
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.
Periodic SAP (Service Advertisement Protocol) is used in IPX based networks to allow 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.
Discard Serialization Packets, when enabled (checked), causes the IPX router to discard Novell
NetWare File Server serialization security frames received from the specified virtual IPX port.
Novell NetWare File Servers implement broadcast frames, often referred to as security frames,
that contain serialization information regarding the license of the file server executable. This
feature permits filtering of these broadcasts to help reduce WAN traffic and is not intended to
interfere with copyright protection mechanisms. This feature is automatically turned on when Dial-
On-Demand is enabled in PPP port setup.
For most applications, the RIP and SAP default timers should not have to be changed. Under
certain circumstances, disabling IPX and SPX Watchdog Spoofing in the Bandwidth Optimization
group has proven effective.
The three IPX WAN Setup windows 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
