This doesn't sound like a NAT issue per se...the cell phone could be acting as a NAT device depending on how you connect to it (such as via wifi).
Have you tried other NAT'd locations besides the router you speak of? Can you provide the NAT traversal settings being used in the Shrew VPN profile? What is the model of the router that you are testing with, and does it have "vpn passthrough" enabled on it? Have you tried connecting the Windows 8 client first (after a router reboot) or does it still fail, and the Windows 7 client works when trying to connect it 2nd?

I am using the same imported configuration file on both a Win 7 and Win 8 laptop. 2. Both the Win 7 and Win 8 laptops can connect to my VPN server without going through NAT (connected via a cell phone hotspot). 3. When trying to access the VPN through a router, only the Win 7 laptop can finish bringing up the tunnel. The connection process on the Win 8 computer pauses and the tunnel never comes up. I tested this using the exact same router with the exact same router configuration. This leads me to believe that the problem lies somewhere on the Win 8 computer. Any ideas or further troubleshooting steps I can take?
