Yes, it's tap. It may be a timing thing.
As Gert said: don't use this unless you absolute have to , and don't use
this unless you know what you are doing.
If you *must* use this feature, try adding
route-delay 5
which will cause OpenVPN to delay for 5 seconds before attempting to add
routes - with any luck, the DHCP assigned gateway will be available on
the client.
