For your end, you should use the local ip/hostname or if it is
dynamic, use %defaultroute. For the remote end, you specify the
remote ip or the remote dns hostname. Openswan 2.6.22 will have
some fixes where dynamic dns did not work as expected (eg when the
name specified did not exist when loading the connection)
