    Set the default INPUT policy to ACCEPT: Edit /etc/default/ufw and set:
    DEFAULT_INPUT_POLICY="ACCEPT"

    Append a drop-all rule to the INPUT chain: Edit /etc/ufw/after.rules, add this line just before the final COMMIT line:
    -A ufw-reject-input -j DROP

    Disable UFW logging (this seems to cause issuses with Scaleway's default kernel):
    ufw logging off

    Enable UFW (don't forget to allow SSH traffic):
    ufw allow ssh;
    ufw enable

    That's it, UFW is up and running, and NBD shouldn't cause issues.
