I think we would need to know more about what it is sending it to. You may have a firewall issue. You may have a
router issue. You may have an issue on the receiving machine.

I'd start with putting a sniffer on the other machine to see if the packet is getting there on the first try. You may
also want to analyze the first two packets that are sent out from your local machine. Check your firewall logs on the
receiving machine.
