What you have done is mis-use the word "gateway". While the more simple

gateway, it MUST lead to the _world_ which is not always the case, and
pretty uncommon when there are multiple ways off of the local wire.

You sir, are awesome. Your explanation was eloquent and descriptive
and I got the point immediately. I have also fixed the problem based
on your feedback. I now understand the meaning of a gateway in this
context.

Glad to hear it! This problem is seen a few times a month, fostered by
the misunderstanding caused by the way windoze shows routing tables with
the 'route print' command (which shows a "gateway" for every route
including the loopback), and an overly helpful Linux routing setup that
accepts a second (or more) default route, and _replaces_ the function of
the existing route (under the impression that you changed your mind).

The 10.x.x.x gateway did not lead to the internet and really, i had no
use for it since all the hosts on that network are on the same switch
as eth1.

Sounds like a helpful tool that was overly helpful. Glad it's working
