Here's the packet trace I promised: http://www.zshare.net/download/72186098494e6f8c/.
As this is a production system, there were a few calls along with the one that interests us. The one you're looking for is that from 5433142...@10.150.65.16 to 5421047...@10.153.66.146. The provider has the address 10.150.65.16 and my box has the address 10.153.66.146.
