You can use ip forwarding (or fast forwarding) to send traffic generated
on the new subnet (172.16.32.0/24) out to your network. But unless you
configure a static route (or setup a routing protocol like RIP), the
other hosts on your network will not know how to reach 172.16.32.0/24 to
reply. So the static route you were trying to add, would need to be
added to every machine EXCEPT the VM Host, which already has an IP in
that subnet.
