trouble with multiple ethernet interfaces on Yosemite?

[jekillen]

I have a Macbook Pro with Yosemite and a Mac Mini with Yosemite.
I have had all my Macs and other machines connected on two separate
networks:
One has connection to DSL modem for internet connects
and the other is isolated by a different manual ip/netmask configuration:
192.168.0. 1-254 netmask 255.255.255.0
and
192.168.1.1-255 with netmask 255.255.255.0
The built in interfaces are fouling up and not connecting when set to
DCHP. They self assign unusable public network addresses.
I have obtained usb-ethernet adapters to set up the second network.
Evne when I can get them properly contifigured, either one network or
the other will not transmit and receive.

Is this lack of router deamon like routd? Or is is some other problem.
I have successfully work with Linix and FreeBSD and Windows systems
on the same local networks. Only the Macs with Yosemite seem to be
fouled up.

Thanks for time and attention.

It reads like 192.168.0.0 and 192.168.1.0 are not routed to each other but you're leaving out too much for me to know what's up. This is one where a picture might help.
