True for port fowarding, but current versions of Openswan (that is,
currently available in most public repos) work just fine with NAT.  I am
using it in NAT environment and I did not have to make NAT/Masquerading
adjustments.  This was not always the case, and the Openswan docs still
refer to adjustments for NAT networks... but as I said it works just fine
for us without adjustments.
