Overview of Internet Extender (NAPT)
Unzip the downloaded package with PKZIP (or similar utility) into a temporary directory i.e. C:\TEMP, then copy all the files except DOSPPD.ZIP to a new directory C:\INTERNET, also download LSppp ISP Dialler and unzip with PKZIP (or similar utility) into C:\INTERNET
Though a file creation utility is included I prefer to manually create the configuration file NAPT.INI with a Text Editor.
NAPT.INI:
- local_pdi=0x60
- remote_pdi=0x61
- local_ip=192.168.000.001
- local_mask=255.255.255.000
LSppp is the easiest dialler I have used to dial my ISP, to automate the process created a Batch file with a Text Editor.
LSPPP.BAT:
- lsppp /dm:o845xxxxxxx /n:3 /B:57600 /U:myname /P:mypass
Copy both these files into the C\INTERNET directory and the copy the contents of the directory to a bootable floppy disk, you will also require the Packet Driver for the Network Interface Card (NIC) to be copied to the disk as well.
After the PC has booted into DOS, the A:>_ cursor will be flashing, you will need to install the Packet Driver and dial your ISP, press enter to execute the line command:
- de22xpd.com 0x60
- This is my packet driver for a Dlink Nic
- lsppp.bat
- This will auto dial my ISP
If you have successfully dialed into your ISP then execute the line command NAPT.INI, this will display a page showing the Local Area Network (LAN) configuration and the ISP Connection configuration, after 30 seconds or by pressing SPACE the next screen appears showing the TC/IP packets sent and received. To exit Internet Extender press ESCAPE, then execute the line commands TERMIN 0x60 and TERMIN 0x61. If the three executables are listed in the AUTOEXEC.BAT file then the whole process can be automated, negating the requirement to have a Monitor.
