This is not possible today.

You can't.  As with "listen on multiple ports at the same time" (which,
effectively, is the same problem: open multiple sockets and listen to
all of them) it is missing functionality that people want, but nobody
was able to implement yet (time, interest, knowledge, ...).

For "multiple UDP sockets" it's supposedly not *that* hard, but the
"UDP and TCP at the same time" case is really complicated as the insides
of OpenVPN are currently handling this very differently.

Sorry.

(One possible workaround would be to just listen on all addresses [with
--multihome!] and use firewall rules to reject packets to addresses you
do not want to see exposed, or run multiple OpenVPN processes - none of
this is perfect)
