I have my HMC on two networks, one private and the other "public". As
per advice found here (merci à Jean-Yves Lenhof), I am running the
private network on eth0 and got DLPAR going fine. I even tried it with
the "public" network disconnected, just to be sure. All is well there.
Getting the "public" network going, however, is causing me grief.

I have the HMC configured thusly (HMC version 3.2.6):

eth0
IP: 192.168.0.100 (private)
Mask: 255.255.255.0
eth1
IP: 10.XX.198.48 (public)
Mask: 255.255.248.0
Default Gateway: 10.XX.192.1 (the router interface)
No static routes specified.

From the HMC, I ping 10.XX.192.1, and it goes out through 10.XX.198.48
and finds it. When I ping outside of the 192 subnet, however, it tries
to go out of 192.168.0.100 and fails.

I should add that the gateway (10.XX.192.1) does not show when I do a
netstat -rn. And of course, I rebooted the HMC.

What am I missing?

Got it! I tried adding this static route to get to all subnets:
Type: net
Address: 10.0.0.0
Gateway: 10.54.192.1
Mask: 255.0.0.0
That didn't work. Turns out I have to specify a static route for each
subnet I need to get to. With everything as per my original post, I
added the route:
Type: net
Address: 10.XX.200.0
Gateway: 10.54.192.1
Mask: 255.255.248.0
Now I can see the 200 subnet. If I need other subnets, I can just add
them, too.

Maybe this information can help someone.
