2.2. Assumptions about the Local Area Network

Some specific assumptions about this sample network are:

Three workstations and a Server are connected with Ethernet cabling:

• a FreeBSD Server ("Curly") with an NE-2000 adapter configured as 'ed0'
• a Windows-95 workstation ("Larry") with Microsoft's "native" 32-bit TCP/IP drivers
• a Windows for Workgroups workstation ("Moe") with Microsoft's 16-bit TCP/IP extensions
• a Windows NT workstation ("Shemp") with Microsoft's "native" 32-bit TCP/IP drivers

The IP Addresses on the Ethernet side of this sample LAN have been taken from the pool of "reserved" addresses proposed in RFC-1597. IP addresses are assigned as follows:

Name		IP Address
"Curly"		192.168.1.1	# The FreeBSD box
"Larry"		192.168.1.2	# The Win'95 box
"Moe"		192.168.1.3	# The WfW box
"Shemp"		192.168.1.4	# The Windows NT box

This guide assumes that the modem on the FreeBSD box is connected to the first serial port ('/dev/cuaa0' or 'COM1:' in DOS-terms).

Finally, we'll also assume that your Internet Service Provider (ISP) automatically provides the IP addresses of both your PPP/FreeBSD side as well as the ISP's side. (i.e.: Dynamic IP Addresses on both ends of the link.) Specific details for configuring the Dial-Out side of PPP will be addressed in Section 2, "Configuring the FreeBSD System".
