The port list doesn't get updated correctly when using DVR.

For reference, duplicate bug 1389177 has a bit more information: this happens when selecting the distributed option, but works when the router is centralised. I'm marking this as Medium severity because I'm not sure how widely used the distributed feature is currently (but we already have 3 people reporting the problem). Either way we'll want to backport this to Juno.

    List port for distributed router interface

    This patch fixes an issue that occurs when a distributed
    virtual router (DVR) is in use on a network and a user
    attempts to assign a floating IP address to an instance.

    The existing approach assumes that only standard routers,
    not DVR based router(s), are in use on the network. As a
    result, if you attempt to assign a floating IP address,
    there are no candidate ports shown in the select to bind
    the floating IP address to. The dialog that allows you
    to attach a floating IP address will show a message in
    the "Port to be associated" select of "No ports available".

    This patch ensures that if a distributed router exists
    for the network, the appropriate port for that router
    is displayed in the list of ports.
