If the connection is from a dynamic ip (aka roadwarrior), then use right=%any.
One condition for this is to use either RSA/X.509 or set rightid=
(if using PSK, you will be forced to use aggressive mode because the id needs
  to be sent in the first packet)

Of the connection is coming from a static ip, use right=ip.add.ress

If the client is connecting from behind NAT. make sure nat_traversal=yes
is enabled on both sides and the IP range used before NAT is in the
virtual_private= list on the server.

It might be the case that mixing the two (behind NAT and a static ip) cannot
be configured - or rather cannot be supported by pluto.

Note that restricting IPsec/IKE connections should not really be needed.
Especially not when using RSA/X.509 connections and not PSK, since it's
pretty impossible to do damage attempting to connect without the proper key.
That part of openswan is coded with very tight security concerns.
