Greetings!

I updated my Ubuntu Server 12.04.4 LTS yesterday using `sudo apt-get
dist-upgrade`, and now, my two-NIC setup, which worked before the
update, doesn't work. Per the instructions located at
http://askubuntu.com/questions/310355/networking-with-multiple-nics, I
set up another route (a few weeks before the update yesterday) and it
all worked great. Now, since the update, something has gone wrong and it
doesn't work anymore. (I'm guessing something in the updated kernel?)

At any rate, here is the content of my `/etc/network/interfaces` file:

--------------------

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth1
iface eth1 inet static
        address 10.0.3.70
        netmask 255.255.255.0
        gateway 10.0.3.1
        dns-nameservers 127.0.0.1 50.198.180.229
#       dns-nameservers 198.60.22.2 198.60.22.22

auto eth0
iface eth0 inet static
        address 10.0.2.70
        netmask 255.255.255.0
        dns-nameservers 127.0.0.1 50.198.180.229
#       dns-nameservers 198.60.22.2 198.60.22.22

post-up ip rule add from 10.0.2.0/24 lookup 101
post-up ip route add default via 10.0.2.1 dev eth0 table 101
post-down ip rule del from 10.0.2.0/24
post-down ip route del default via 10.0.2.1 table 101

---------------------

And here is the output of `ip route show`:

default via 10.0.3.1 dev eth1  metric 100 
10.0.2.0/24 dev eth0  proto kernel  scope link  src 10.0.2.70 
10.0.3.0/24 dev eth1  proto kernel  scope link  src 10.0.3.70

And the output of `ip route show table 101`:

default via 10.0.2.1 dev eth0

Finally, here is the relevant part of the APT history log,
`/var/log/apt/history.log`:

I didn't select a package because I'm not sure at what level this
problem exists. If any of you have a better idea as to what the affected
package might be, please let me know and I'll update (if I can) this
ticket.

Thank you so, SO much for your help with this!

Best Regards,

Spencer
