LANtastic Network Operating System Version 4 Compatibility Bulletin
Product Reviewed: Pathway/Access Release 2.0 and WIN/ROUTE Release 2.1 by 
		  The Wollongong Group
Classification:  TCP/IP Connectivity

Compatibility Statement:
Pathway/Access Release 2.0 and WIN/ROUTE Release 2.1 are compatible with 
LANtastic NOS 4.xx.

Product Overview:
The Pathway/Access and WIN/ROUTE products can be used together to provide 
TCP/IP connectivity between a PC-based LANtastic network and a variety of 
machines that are connected on an Internet network.  A dedicated PC running 
WIN/ROUTE provides the link between the LANtastic and the TCP/IP world, 
while Pathway/Access provides TCP/IP transport layer and applications services 
for the LANtastic side of the link.  In general, the Pathway drivers convert 
LANtastic's standard NetBIOS packets into TCP/IP format, allowing IP-based 
applications to establish links via the WIN/ROUTE router.  We tested and found 
compatible the TELNET terminal emulation program, FTP file transfer utility, 
FTPD file transfer server, PING network communication test, LPR remote 
printing utility, and the Berkeley R-series commands RCP (remote copy), RSH 
(remote shell), and RLOGIN (remote login).

Test Equipment Configuration:
The following machines were used for Pathway/Access-WIN/ROUTE testing.  All 
machines running LANtastic used Artisoft AE-2 or AE-3 NICs and testing was 
completed using LANtastic NOS v4.1.  Machines running as LANtastic peer-to-
peer servers are designated by (S).  

	-       CompuAdd 325:   386DX/25, MS-DOS 5.0 (S)
	-       Tandon 486/33:  486DX, MS-DOS 5.0 (S)
	-       Northgate 386/20:       386DX, MS-DOS 5.0  (WIN/ROUTE host)
	-       Altima 286:             286/16 portable, MS-DOS 4.1
	-       Clone 286:              286/12, MS-DOS 3.3
	-       CompuAdd 333:   386/33, SCO UNIX System V/386 Release 3.2 v2.0

A Western Digital WD8003E network adapter was the network interface for the 
UNIX system.  The dedicated router used both an AE-2 and a WD8003E card to 
route packets between the DOS and UNIX systems.

Installing and Running WIN/ROUTE:
Installation of both Pathway/Access and WIN/ROUTE is accomplished by 
running a batch file included on the installation diskettes.  We recommend 
installing WIN/ROUTE before installing Pathway/Access, since the router must 
be operating properly before TCP/IP services can be used from a LANtastic 
station.  The router PC must be dedicated to the function of routing and cannot 
be used as a LAN workstation.  It requires two LAN adapter cards, one for the 
LANtastic side of the network and one for the TCP/IP side.  In the example 
depicted in Figure 1 above, the LANtastic interface card is an Artisoft AE-3 
adapter and the Western Digital WD8003E card is used for the TCP/IP interface.  
WIN/ROUTE installs to a directory called WINTCP from a single program 
diskette.  The install routine appends the following  line to the CONFIG.SYS 
file:

   DEVICE=C:\WINTCP\WINTCP.SYS

The WINTCP.SYS driver is really a data structure that holds configuration 
information for the routing TCP/IP kernel, ROUTETCP.EXE.  Before the kernel 
can be run for the first time, this information needs to be configured, or 
"customized," via the CUSTOM program.  The WIN/ROUTE documentation 
covers the appropriate values for the configurable parameters, but there are 
some that must be set to specific values.  These are:

	1)  Set the number of interfaces to two (2).  This number is the number 
	of network adapter cards that are installed in the router.

	2)  Set the Internet (or IP) address for each interface.  The actual 
	addresses depend on what IP addresses are assigned to the site.  If 
	there are no IP addresses officially assigned to the site and the LAN 
	will not be connected to a larger network, these addresses can be 
	arbitrarily determined.  You must, however, make sure that the correct 
	IP address is assigned to its proper interface number.  See the 
	"Hardware customizing Procedure" section in Chapter 2 of the "WIN/ROUTE 
	Installation and User Guide" for details. Refer to the WIN/ROUTE and 
	Pathway/Access documentation for general information regarding IP 
	addressing.

Once customization is complete, reboot the PC to effect the new configuration.

Starting the router is a matter of running the drivers for the adapter cards and 
then bringing up the routing kernel and software.  As mentioned above, the 
router must be a dedicated machine.  In the  protocol stack shown in Figure 3 on 
page 2 (Protocol stacks are read from the bottom up, lowest level drivers at the 
bottom to highest level at the top), the AEX.EXE and AILANBIO.EXE TSRs are 
loaded as the basis of the LANtastic network interface.  Wollongong's 
NB_DRV.EXE is loaded on top of them in order to provide NetBIOS to IP 
translation for the kernel.  The other interface - via the WD8003 adapter - is 
pure IP, so Wollongong's WD80X3.EXE TCP/IP driver is all that is needed.  The 
ROUTETCP kernel is then loaded to provide basic TCP/IP transport layer 
services, and WINROUTE runs as the top layer, providing the packet routing 
function.  The following is a sample batch file for loading all the required 
software for the router:

   AE2 IOBASE=340 IRQ=2
   AILANBIO
   NB_DRV -N:60
   WD80X3 -I:3 -M:D800 -B:280 -N:61
   ROUTETCP
   WINROUTE

Important Note: In order for the router and the UNIX computer to communicate 
properly, the address of the router must be added to the TCP/IP routing table on 
the UNIX machine.  Refer to Chapter 3, "Setting Up Routes," in the WIN/ROUTE  
Installation and User Guide  for specific instructions.


Installing and Running Pathway/Access:
The Pathway/Access installation diskettes contain both the network interface 
drivers and the application programs (e.g. FTP, TELNET, etc.).  The installation 
process places the files in a directory named PATHWAY on the hard drive.  
Additionally, it appends a line to the CONFIG.SYS file that loads the 
PWTCP.SYS driver.  This driver is similar to the WINTCP.SYS driver and 
contains configuration information that is used by the Pathway kernel program, 
PWTCP.EXE.  As with the WINTCP.SYS driver, use the CUSTOM program to 
customize the PWTCP.SYS information so it can be used by the kernel.  
Variables such as the Internet address, host name, and username for a 
particular PC are set using CUSTOM.  Appropriate values and ranges for these 
settings are documented in the Pathway/Access Installation Guide, but there are 
some that must be set to specific values to ensure correct network operation.  
These are:

	1)  The Default Gateway address must match the Internet address of the 
	LANtastic interface on the router.  Set it using the "Set default 
	gateway's address" selection on the main CUSTOM menu.

	2)  Using the "Select program parameters" selection from the main 
	CUSTOM menu choose "Set expert parameters" on the Program 
	Customization menu.  Set the number of "large packet buffers" to 10 and 
	their size to 512.

Reboot the PC once customization is complete to load the new values.

Figure 2 on page 2 shows the protocol stack for the PCs on the LANtastic 
branch of the router.  As it suggests, all of the LANtastic TSRs are loaded 
before running any of the Pathway/Access programs.  The LANtastic NOS TSRs may 
be loaded into upper memory on machines with support for upper memory 
functions, but the Pathway TSRs should be loaded in low DOS memory.  After 
loading the desired NOS programs, run the Pathway NB_DRV.EXE and 
PWTCP.EXE programs.  As with the router, the NB_DRV driver provides IP to 
NetBIOS translation, and PWTCP is the support layer for TCP/IP applications.  
The following batch file could be used to run both LANtastic and 
Pathway/Access on a typical PC:

   AEX IOBASE=340
   AILANBIO
   REDIR TEST LOGINS=10
   NB_DRV
   PWTCP

Once the above batch file has run, TCP/IP applications such as PING, FTP, and 
TELNET can be used to access the IP network.


Compatibility Notes:
Artisoft has successfully tested the PING, FTP, FTPD, TELNET, RCP, RSH, 
RLOGIN and LPR functions in the configuration outlined in the Test Equipment 
Configuration section above.  In addition, Pathway/Access includes a Windows 
3.0-based program that includes FTP, TELNET and LPR services.  We tested 
this utility and also found it compatible with LANtastic and LANtastic for 
Windows.  Running FTPD in "background mode" (using the -b command line 
switch) is not supported.
