No link speed or bandwidth issues, but your network will not be able to
see anything within the 192.168.9/24 prefix (other than what is within
your /27).

All devices within your network will never go to the default gateway to
route externally like they should, as all devices will think that the
rest of the /24 is internal, rendering the subnet unreachable.

Either render a /24 prefix on the router's fast Ethernet interface, or
change the internal hosts to /27 as well.
