openswan automatically tries to determine if it is "left" or "right", so you
can re-use the same connection on both ends.

however, when using roadwarrior and server connections, that is on the
client with left=%defaultroute and on the server with right=%any, you
cannot do this, because you would have to specify both "%defaultroute"
and "%any" in the same connection and then openswan cannot determine
if it should be the client or server side.

For all other cases, eg static VPN tunnels, you can re-use the exact
same conn.
