As I see the rekey=yes is enable by default, or I'm missing something?

What do you mean with keep a connection up? Currently the tunnel stay
up with and without regular ping. The problem is that I cannot use the lan
on the openswan side from the vigor side, i.e. ping from vigor to openswan
gateway doesn't work, while the contrary works. But starting after the first
ping from the openswan side I could use all the services from the vigor side
for about 30secs ... and the tunnel still always up. I've already 
tried to remove
the regular ping but all the tunnels are always up!
