IP, IPX, and AppleTalk Dial-Up Environments 5-1

IP, IPX, and AppleTalk Dial-Up

Environments

Remote node users are telecommuters and mobile users who need to dial in to a network from their

PC or Macintosh computer, through an access server in to IP, IPX, or AppleTalk networks to access

network resources. This chapter describes the following scenarios:

• Getting a PC to dial in to a network by using a PPP application to access IP resources

• Getting a PC to dial in to a network by using a PPP application to access Novell IPX resources

• Getting a Macintosh to dial in to a network by using ARA to access AppleTalk and IP Resources

Note This guide does not describe how to conﬁgure SLIP. For more information about SLIP, refer

to the Dial Solutions Conﬁguration Guide. For popular conﬁguration tips gathered by Cisco’s

Technical Assistance Center (TAC), go to the “Sample Conﬁgurations” home page at

http://www.cisco.com/warp/public/700/tech_conﬁgs.html.

Each conﬁguration in this chapter builds on preceding conﬁgurations from previous chapters. It

presents the whole conﬁguration required to enable dial-in and conﬁgure security for each of the

scenarios. Thus far, this guide has described how to conﬁgure the following on your access server:

• Autoselect

• Group asynchronous interfaces

• Modem dial-in

• Security

When a remote PC or Macintosh computer dials in to a network, it is considered a “node” on the

LAN to which it is connecting. This is the case for each dial-in session, whether the device dialing

in is a PC, Macintosh, or other computer. The IP address of a PC, for example, is selected from those

available on the subnet assigned to the network that the PC is connecting to. In Figure 5-1, for

example, the telecommuter’s Macintosh is a node in the AppleTalk network 2500 in the zone

Mac-dialup, and is treated like a local host.
