Hetzner server issue

samipysamipy Member

I am currently running Hyper-v virtual machines on hetzner server with /27 subnet, today they blocked the server stating "The IP ..*/27 seems to be not used but it looks like you are forwarding all incoming traffic back to our router.

What should I do to fix it ? Any help ?

    Do ip route add blackhole your_prefix/27 dev lo to prevent sad Hetzner

    Currently you have loop due to fallback to default route

    Is that really the reason they would block the entire server though? Nothing else?

    Thanks, but my server has windows OS.

    Unfortunately, yes.

    You could create another tiny VM and assign all unused IPs to it. That would prevent the loop back to their router.
