I can't seem to confirm that behavior.  I have both sides setup with the
leftsourceip to the local internal ip address, but I have no problems
talking to public side.

I have tried from a workstation to the public ip on the remote gateway,
and it works just find and tcpdump says it is unencrypted.  I have also
tried from a gateway to the public ip on the other gateway, and I can
connect to it and tcpdump also says that I am doing it unencrypted as

I just can't find anything that doesn't work better by setting this
parameter.  What am I missing here?  Is there a test I could run that
might give me some insight?
