Yes, all the data from the ALLOW statement on nimbus

Yes.  BTW the accept statement is not needed except to request data from
WSI, I would delete them..

That's your option, decode the data on tornado1 and the use pqsend program
to send it to a down stream site or decode the data at each machine.  The
first option is more efficient but it requires you  to set up the
configuration to send the data downstream, scripts etc.  I don't have any
scripts on hand that perform that task.

Take care Dan,
