I have a little problem and only wanted to know if I'm right.
MachineA: 192.168.11.17 - http://www.cloudshark.org/captures/d93b8cda3ebd
Sorry for Checksum Offload here!
MachineB: 192.168.13.17 - http://www.cloudshark.org/captures/6fec5b3aa134
There's only the one stream in my trace file. What's going on there?

Well, there are some differences. Some minor, some major.
Minor: Some frames with the same IP ID are different in length: #3,#5,#8. However, that's not a problem, as the difference is due to removed padding bytes in the ethernet frame.
Major: Frame #18 (MachineA) was not transmitted over the VPN tunnel, as the size was too large (4192 bytes) and the don't fragment flag was set in that segment.
If your question is: How to fix the 'major' problem?
My answer would be: Check the MTU size of the involved systems and adjust it to the requirements of your VPN, or allow IP fragmentation.
