Internet Extender (ver 1.0b) Abandoned Freeware Internet Extender allows you to convert a DOS PC into a dedicated NAT Router. You can interface the router using either a modem and a NIC (the real advantage over most other routers), or two NIC adapters. Note that unlike most other DOS software availible on this website, I have NOT pre-configured it for you (you will have to read the directions and set it up yourself to match your unique system requirements). DOS, being a very stable SINGLE-TASKING operating system, it an excellent operating system choice for machines designed to perform a SINGLE DUTY. inet_ext.zip = the Internet Extender program (includes the manual) iesource.zip = sourcecode (-NOT- required)
