SMB access via VPN (subnet issue?)

Hi

I have an instance of openmediavault providing SMB. I can access files locally ok (192.168.1.182) but I'm trying to configure the VPN server that I run of RaspberryPI 4 (pivpn) (192.168.1.50). The open VPN connects fina from WAN, I can browse the internet as if I'm home. The problem is, the VPN server puts me on a subnet (10.8.0.2) when connected and I'm not able to detect shares.

I understand this is the desired behaviour, my previous router came with openVPN server and I was able to log in to my local network to access the files, Id like to replicate this again since my old router is retired. I played with WINS but without much success

Any pointers?
