VPN: step-by-step

I tried this but still can’t play to my laptop’s audio while VPN’d in.

I can connect to the Core and control all of the endpoints on my LAN though. My setup is:

Roon Core and Open VPN both running on QNAP NAS - 192.168.0.90

LAN: 192.168.0.x with a mask of 255.255.248.0 (Configured on router)
If I understand correctly, this makes the list of valid ip’s 192.168.0.2 - 192.168.7.254

QVPN ip pool: 192.168.2.2 - 192.168.2.254

Laptop is getting 192.168.2.6 with a mask of 255.255.255.252

What am I missing? Need to adjust the masks somehow?
