Can I configure a Linux (PC) box to act as a gateway between a small LAN of 5 PCs running LANtastic and our TCP/IP ethernet? I'm afraid I know nothing of DOS LANs.

Linux can allow you to configure it as a ip router, bridge, ipx router between 2 lan. You need to install 2 lan cards on your linux box. Becareful when you using 2 ne2000 compatiable card, linux will not auto probe the second lan card(messages " delaying initialization eht1"). You also need to configure your LANtastic to run TCP/IP, because I am not familiar with LANtastic, detail configuration on LANtastic my refer to LANtastic TCP/IP topic.

I also need to known your TCP/IP lan configuration, are you connecting  the lan to internet ? Do you get official ip for your TCP/IP lan, if you get the official IP, perhaps 1 class C ip address, you need to subnet your class C ip to 2 parts, with netmask(255.255.255.128) to separate the 2 lan.

If you TCP/IP lan not connect to internet, you can assign your 5 pc lan to any ip address (eg. 192.168.0.0 network), with your linux router one card's ip configure with x.x.x.x, where x.x.x.x is one ip of your TCP/IP lan, and another lan card config with ip  to 192.168.0.1, set your default route on linux to the router on your tcp/ip lan, and set your LANtastic ws gateway/router to point to 192.168.0.1. You also need to config your TCP/IP lan's routing table to add route 192.168.0.0 network through gateway x.x.x.x.

There is a DOS base router call IPROUT(refer to www.iproute.com) which is much easy to configure than Linux. Although it is little bit slower. The configation concept is similiar to my answer on above.
