Access to Vero4k from VPN

Hello, i have a specific networking problem and i’d much appreciate some help.
I have Asus router ( with openvpn server running on it (TUN,, so i can have access to my home network from the outside. On my Vero 4k ( i have Surfshark VPN, managed through Zomboided. If i’m on my home network, i can normally access Vero4k (NAS, Transmission etc). But when i’m connected to my home network via VPN, i cannot see Vero4k or access NAS etc. I can do that only, if i disconnect Vero 4k from the Surfshark VPN. Any hints? Thank you.
