You are right. When a client asks about the location of a volume, it is
given a single IPv4 address for each replica and assumes that there will
be a Coda server that knows about the replica at that ip-address
listening on the (hardcoded/reserved) port 2432/udp.

As a result, you cannot run more than a single server per ip-address and
multi-homed hosts have some issues as well when some addresses are not
reachable from f.i. the internal network.

Things will improve, but there is not a simple fix that would make
things work correctly at the moment.
