Sorry to be pessimistic, Jim, but I think it's going to be a problem. Maybe someone on the Bunny could help? There are or were several Linux users over there.
BTW, I tried to do almost the same thing here some months ago. I have a gateway running the LAN in our house here and connected the Ami up to it. I was unable to get Miami to handle the gateway, though. It kept on clearing the gateway address out to 255.255.255.255. Never did find out why, I had to use Genesis eventually. The gateway box runs MS-DOS.
