If you have a recent version (NGX), you can use the Link Selection
feature (under the
VPN properties on your cluster object), and then say that your cluster is
"Statically NATed" behind NAT.

I don't know what unsupported workaround you are talking about, but if you are
referring to adding a fake external interface, this should work if you
enable the
dynamic interface resolving mechanism. :-)

HTH - Good luck!
