But if you send a PR that makes it possible to derive the port nr for the destination from the port nr of the listening socket, then that'd certainly be welcome and we'd merge it after review.

[systemd-devel] redirect multiple local ports to corresponding remote IPs / ports?
systemd directive ListenStream and systemd-socket-proxyd is really useful. Let's say I want to redirect... ListenStream=80 ListenStream=81 etc. ExecStart=/usr/lib/systemd/systemd-socket-proxyd Is there during ExecStart some way to get the ListenStream port? I.e. ExecStart=/usr/lib/systemd/systemd-socket-proxyd 10.152.152.10:${PORT} I mean, if - ListenStream=80 -> ExecStart=/usr/lib/systemd/systemd-socket-proxyd 10.152.152.10:80 - ListenStream=81 -> ExecStart=/usr/lib/systemd/systemd-socket-proxyd 10.152.152.10:81 etc. Or can there be a wrapper that has access to the ListenStream port number? If you are wondering what I am trying to do... I am trying to port anon-ws-disable-stacked-tor from loads of mostly idle socat listeners to systemd socket activation. Ideally, rather elegantly without one systemd unit file per port redirection.
