IPX Setup

Internetwork Packet Exchange (IPX) is the network protocol used by Novell NetWare networks. This chapter shows you how to conﬁgure the Netopia R9100 for routing data using IPX. You also learn how to conﬁgure the router to serve IPX network addresses.

Note: Most cable modems do not currently support the IPX protocol over the WAN. The Netopia R9100 supports IPX routing over the Auxiliary port with an attached asynchronous modem. This requires the optional add-on dial-in kit (order TER/AD1).

This section covers the following topics:

■“IPX features” on page 10-1

■“IPX deﬁnitions” on page 10-1

■“IPX setup screen” on page 10-3

■“IPX routing tables” on page 10-5

IPX features

The Netopia R9100 supports the following IPX features:

■IPX RIP and SAP

■NetBIOS broadcast packet forwarding (IPX type 20)

■IPX packet ﬁltering deﬁnable by source and destination IPX address and socket number for added security

■IPX SAP ﬁltering to aid in optimizing WAN bandwidth

■Dial-on-demand features:

■Spooﬁng of IPX keep-alive, SPX, and server serialization packets

■Conﬁgurable RIP/SAP timers on connection proﬁles

IPX deﬁnitions

This section deﬁnes IPX-related protocols such as RIP, SAP, and NetBIOS, in addition to other related terms. See the next section for setup instructions.

Internetwork Packet Exchange (IPX)

IPX is a datagram, connectionless protocol that Novell adapted from Xerox Network System’s (XNS’s) Internet Datagram Protocol (IDP). IPX is dynamically routed, and the routing architecture works by “learning” network addressing automatically.
