The issue with USE_NAT_TRAVERSAL_TRANSPORT_MODE is not wether or not it
was causing problems in the implementation, but that as a feature, it is
a security risk. Openswan tends to package with all dangerious options
disabled, leaving them open for the (hopefully somewhat cluefull) user
to enable. One such example is 1DES. NAT-traversal in transport mode also
has security implications. That is why it is disabled.
I will leave it up to Michael wether or not to change the current behaviour.
