Access USB drive using VPN

I have a ext4 drive connected my AC68P running Merlin, I want to be able to access this drive from the Internet

So I started up a VPN server.
Server Port: 1196
Everything else is default.

I exported the .opvn file and started it up on my phone

But when I use esfile manager to connect to 192.168.1.1 it doesn't connect to the samba drive. 192.168.1.1 in Google Chrome doesn't go into the router page either.

Am I misunderstanding the purpose of "Push LAN to clients"?
