How do you do that? systemd doesn't have any support to manage network
connections. It lacks information about the state of the network
devices and cannot configure them as well.
In Matthew's case creating a dispatcher script that issues a
"systemctl restart squid.service" on vpn state changes looks like a
correct solution to me. Do you have a better idea?
