Custom routing table.

I have an Ubuntu system that uses two wired networks simultaneously (PCI Ethernet, USB Ethernet). I would like it to use the USB wired network for internet access and the PCI wired network for accessing the internal network (e.g., 10.0.13.120, 10.0.13.134, 10.0.12.1, 10.0.10.16, 10.0.10.17, etc).

1.
