This shows to me that the interface is not being brought up on boot.

Is there a line that says 'auto eth0' in your /etc/networking/interfaces file?

Instead of doing 'ifconfig eth0 polar...' and 'route add -net...' try
'sudo ifup --verbose eth0'  If that fails then there _is_ something
wrong with your configuration file.

A normal /etc/network/interfaces file looks something like this:

# The loopback network interface
auto lo
iface lo inet loopback
# my network
auto eth0
iface eth0 inet static
