from man ifconfig:
alias Establish an additional network address for this interface. This
is sometimes useful when changing network numbers, and one wishes
to accept packets addressed to the old interface. If the address
is on the same subnet as the first network address for this
interface, a netmask of 0xffffffff has to be specified.
so, change this...
ifconfig_fxp0_alias0="inet X.X.X.17 broadcast X.X.X.X netmask 255.255.255.224"
to this...
ifconfig_fxp0_alias0="inet X.X.X.17 broadcast X.X.X.X netmask 255.255.255.255"
and you should be good to go.
