   And, with that simple statement, you have solved my problem.   
   /Of course/, wordsworth needs a route back to sysdev2. And, in the   
   environment I'm trying to model, that route would be supplied by   
   a NAT rule on sysdev1.

   Thanks, Henrik. You've hit the nail on the head.   
   And now, I'm off to make some firewall rules.
