I'm working on and experimenting with a new setup with home network
and also changing over from dsl to cable. Right now I have both.
What I'm after right now is a way to set up networking on both
outgoing networks from the same machine. And I have some thing in
place that does most of it. M2 in the diagram is linked by ethnet to
1 different Netgear routers. One is the gate way to dsl modem the
other is gw to an openbsd router and then to the cable gateway.

more machines
There are more machines at the level of M2 all on a Netgear hub. But
not important to my mission.
I have both nics working on M2 and can run with the dsl as main route out.
Routing table looks like:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth1
In that scheme 192.168.0.1 is the address of NEGEAR router leading to
dsl modem And 192.168.0.8 (shown as network 192.168.0.0 on eth1)
above.
Any attempts to connect out automatically go over:
192.168.0.8 => 192.168.0.1 => DSL MODEM =>
Now if I bring up eth0 192.168.1.7 on M2
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth1
I can ping stuff like M1 in diagram netwrork 192.168.1/24 but if I
set a static route to connect to internet out that door it seem
traffic that would have gone out the 192.168.0.1 will now go out
eth0 (192.168.1.7) Like it has taken over as default route.
If I add a route to the other internet gw
(And I'm not sure of what all I can do with route)
route add 192.168.0.20 gw 192.168.1.9
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.20 192.168.1.9 255.255.255.255 UGH 0 0 0 eth0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth1
I can now ping 192.168.0.20 from M2
Or set routes to internet hosts:
route add -host some.inet.com gw 192.168.0.20
And I can get there over the correct route.
Lots of route adding if you intend to do much.
I wondered if there is someway to have on xterm that has the
secondary environment for a network setup. While other xterms use
the primary or default setup.
Anyone here that has done something like that?
