Yes. I use it (see my previous mail). But it is not documented in openVPN, and the use of a port value of 0 in bind() hardly. In the source the --lport value is sent to bind() directly, so it happens to work. It would be great if --lport 0 were mentioned in the manual, to avoid breaking this behavior in the future. Mickael
