[systemd-devel] systemd-socket-proxyd usage: remote's directly ping-/telnet-able, but via proxy "Network is unreachable"?

[PGNd]

Simple fix.  As usual, 5 minutes after posting ...

With a helpful prod @ #irc to look at what PrivateNetwork does @ http://www.freedesktop.org/software/systemd/man/systemd.exec.html

    "If true, sets up a new network namespace for the executed processes and configures only the loopback network device "lo" inside it."

Then changing,

- PrivateNetwork=yes
+ PrivateNetwork=no

does the trick.  Remote SMTP now accessible over the establish proxy link.
