I can connect to my VPN server and ping the devices in its same network but nothing else

[BlueSialia]

So I connect to my VPN server, which is my home router. But then I cannot access the web GUI of my router or VNC into my Linux virtual machine or use Moonlight Streaming to connect to my Windows virtual machine or access my Plex server web GUI or access my network shares...

I can ping all those devices though. I suspect my local router (not my home router which is my VPN server) is blocking something because if I use my phone hotspot I don't have any issues. What is being blocked?

Local router is a Vodafone HG658c and home router is a Linksys WRT1900acs if that helps. And here is my client configuration file.
