I'm not entirely sure I understand this question.  And what is `localnet',
anyway?

I think your default routes are the problem.  Outgoing traffic will always
use the *first* route that matches, so you're sending generic internet
traffic to 10.10.10.1.  I don't know your network topology, but since this
is a private IP address and you've explicitly listed your ISP's gateway on
the other default route, this is most probably not what you want.

I'm a little unclear how the Debian netconfig stuff works with multiple
networks, but I suspect you should remove the gateway entry from the eth1
section of /etc/network/interfaces, then restart your network system
(/etc/init.d/networking restart).
