I used the output of "nmcli dev list iface eth0" to populate the blanks in the gnome-control-center network 
panel:

DNS section - entered dns ip

Routes section - entered ip address, netmask, gateway ip

..and finally things work.

I noticed that this changed "/usr/local/etc/NetworkManager/system-connections/Wired Connection 1"

[802-3-ethernet]
mac-address=24:B6:FD:FA:E1:60

[connection]
id=Wired connection 1
uuid=ed68afcc-88f2-45a4-b920-67a8a929eb4b
type=802-3-ethernet
timestamp=1396795087

[ipv6]
method=ignore

[ipv4]
method=auto
dns=10.180.1.10;
route1=10.180.20.123/24,10.180.20.1,0

..by adding the last two entries.

What I don't understand is why networkmanager cannot do this automatically - is it because the default "Wired 
Connection 1" has spaces in the name (?!) or is it some sort of dbus/polkit/linux-pam permissions issue?
