Some references suggest that you *also* need to say Wants=network-online.target [1]. It might be that network.target is sufficient if you just bind to "*", but considering that we're not mentioning that either right now, I don't see a need to discuss the difference. (Down the road, maybe we should consider using IP_FREEBIND on Linux, as suggested at [1] ... although that hobbles error detection, so I'm not really sold that it's such a great idea.) regards, tom lane [1] https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/
