R7800 can't see shared SMB folders through VPN

Hi,

I started using the VPN service on the R7800, and I can use Microsoft's Remote Desktop connection app on iOS 9.3 to connect to my home computer (Windows 8.1) through the internet as if I was on the LAN (192.168.1.2). However, apps which read shared SMB folders don't detect them (Infuse 4 pro). Similarly, on my Nexus 6P, Solid Explorer can't open the shared folders when connected through the VPN. Is it possible to read shared SMB folders from Windows remotely through the VPN on the R7800?

I have also tried to ping 192.168.1.2 from my iPad and there is no response. When I ping my Android devices, they do respond though. But, again, RDP to that computer works, so I'm not sure what's going on, anyone with more knowledge can help?
