Hello, my effort to to route my LAN traffic via the OpenVPN tunnel is failing, although
curl ifconfig.me from the OpenVPN device shows OpenVPN device is tunneling. However the LAN Traffic is not being forwarded to the Internet VPN Gateway. Please review my routing table below for a fix.
Lan------------------→ VPN-device --→ ISP Router ------Internet Cloud------------→ VPN Gateway
192.168.188.0/24-→192.168.188.48-→ISP Router- 37.120.209.219

It appears that I need to route the LAN through the tun0 Interface on the VPN device.
ip forwarding was enabled
