Actually it has a leftsourceip line, which is what you mean, I think.

If you specify leftsourceip it makes the pluto _updown script add "src
<address>" to each "ip route add" it does. So if you change the route,
you'll need to add that as well.

Should be "ip r change 10.0.0.0/8 dev eth0 mtu 1470 src 10.15.1.1"
