Description of problem:

If a client is given a subnet mask where the router is outside of it as of dhclient 4.1.1-60 it no longer works due to the change to fix BZ#1527995.

This appears to be due to the fact it won't run the code unless is_router_reachable is true, which was not the case previously.
