in version 3 this worked
ipsec setup restart
but I am not sure if it is solid on version 4.
Are you in a position to test it ?
That's very close to what I'm looking for and does work, thanks very much. Is it possible to reset a particular tunnel as opposed to all the tunnels, which is what this command will do?
Thanks very much for your help!!
Actually I was a bit hasty.
Your tip gave a place to start but the real command is
ipsec auto --down <connection name> to take a tunnel down and correspondingly;
ipsec auto --up <connection name> to bring the tunnel back up
