While the advice about setting addresses in unbound was good, my
advice would be "don't do that." Depending on IPs on the same
interface to be routed differently will just cause endless pain.

Linode says you can set up a VLAN for free.  Why not do that,
and put the shortcut on a separate interface?  Then everything
should work without any funny configuration.
