If anyone is interested, I've got the following setup working:
ISP <---> ADSL modem <---> Hub
NetBSD box (Gateway)
MacOS MacOS Window-95 NetBSD
I have an internal network with multiple machines connected on an
ethernet. Also on the ethernet is my ADSL modem for external network
access. I have IPNAT running to give me Internet (external) network
access from all my internal machines through a single IP address
dynamically assigned by my ISP using DCHP-client. I can also access all
my internal machines from any system on my inside network, including the
NetBSD gateway box. Access to the NetBSD box can be by internal name
using my inside IP address (192.168.1.16) or by external name using my
outside IP address (208.x.x.x). Samba filesharing is working for Windows
clients and NetAtalk filesharing is working for MacOS clients all on my
inside network. Apple File Sharing also works between MacOS systems.
And to top it off I have the NetBSD box configured to serve out the IP
addresses to my inside machines using DHCP-daemon.
So it is possible to do all this with a single ethernet connection on the
NetBSD system. I'm sure it's obvious how to do this for someone who
really understands this stuff, but it took quite a bit of head scratching
on my part. I think it's pretty simple to convert my setup to use
multiple ethernet interfaces or a ppp link to the Internet world. In
fact prior to getting my ADSL line I used this on a ppp link.
I'd be happy to put all my configuration files together for others to
start with if anyone thinks this would be useful. I've also got some
scattered notes about how to beat MacOS and Windows-95 into submission
with this setup, and I have some old notes about how to connect to the
NetBSD box using PPPD and SLIP which I've done with an old MacPlus system.
