When I increased the timeout in my firewall for these port 700 UDP "connections", that made my circuit much more stable. Like Peter said, Peter and I had a big debate about this at lunch today. UDP is, by definition (or so I thought), both stateless and connectionless. I can't understand what state or connection is being timed out in this case.... Bob
