Now that IP shows up in the gateway column when I run route. I think it's a
good thing. Ping to 10.14.8.X doesn't complain anymore about unreachable
host. I'm still not getting anything back, but that may be the other side's
intention (or misconfiguration)
It's just that OpenS/WAN sometimes seems to be unable to figure out

Yup, I'm getting that now (as route -n shows).
Usually, you need only one of them.

The man page says "Relevant only locally, other end need not agree on it".
So I think, as I'm "left", the parameter rightnexthop will be ignored. And
I should take it out to reduce confusion.
