Ihand transcribed them from the linux monitor to the mac. Sorry about bad

the Mac LC 475 has the following in the "TCP/IP" control panel:

The above is correct except for the hub, there is none. The cat-5 cables all go
directly
to the router. There is one cable from the router to the DSL modem ( or adapter)

There are 3 choices for the router configuration; manual, DHCP, and BOOTP.
I have always used "manual" in the past.

Not using DHCP, so I assign the addresses
192.168.1.2 (mac #1)
192.168.1.3 ( mac#2)
192.168.1.4 ( linux box)

If static assignments are the same as manual, yes.
