The static route on the host would prevent the redirect.

Adding a route to just the Comcast router is simpler
configuration wise, and sufficient for low traffic clients.
However, that means the Comcast router will "handle" all traffic
bound for the internal subnet. Therefore, if any of the external
subnet clients are high traffic, you should manually add a route
to those clients as well.
