    This bug is present since many years.

    :-)


    Currently, tt's not possible to declare a network like this :

    | IPv4: 54.37.96.xxx/32
    | Gateway: 54.38.179.254

    The installer tell "Unreachable gateway" but it's not true. If the
    network if configured with these values, everything is fine.

    If i put this in /etc/network/interfaces, it works :

    | auto eth0
    | iface eth0 inet static
    |     address 54.37.96.xxx/32
    |     gateway 54.38.179.254


    Which feels wrong.

    It is the /32 that makes it odd.

    Would like to see this bugreport to be closed.

    Yeah that's for sure. The gateway IP is not within the subnet (given
    only one IP is) so it is definitely unreachable by normal IPv4 routing
    rules.

    If it was a PtP link, then perhaps it would be a different story, but
    it probably isn't.

    Certainly for any normal functional network, those settings would not
    work. If they do work, the network is doing things outside normal IPv4
    routing rules.
