TechNet Hybrid Cloud with NVGRE (Cloud OS) Help!

Hi I've gone through this LAB 4 times, start to finish including a complete wipe of all servers. I keep getting the exact same result. I'm  missing something along the way but I cannot figure it out. At the end of the NVGRE Lab my tenant can never ping through. I feel like its an issue on my router but honestly have no idea. My NVGRE Vm can traverse the network fine.

This is my first exposure to NVGRE and have no knowledge how to troubleshoot this issue. Any advice or insight would be great. Thanks
