Route 1 port and Bridge (1 network) through VPN

HI,

I have RB2011UIAS, ROS 7.6 – this is connected to internet on port 1
General network for home is on 192.168.2.0/24, Bridge 1, ether 1-8

I have ethernet Port 9 on Bridge-VPN with IP of 192.168.21.0/24. DHCP server running and active

I have an interface PPTP client VPN setup and running, local IP 104.37.5.52, remote 172.111.166.4 (these are probably dynamic) and connected.

I want to route all traffic from 192.168.21.0/24. through VPN. I want DNS from the network – through VPN too please.

Tried various options over the past 2 weeks - and got frustrated – so back to scratch.

Can some one help me with this ?

Thank you (in advance)

Yes, first remove ether1 from the bridge.
Second, use wireguard its actually a secure protocol unlike PPTP vpn.
Third,
If the entire subnet is to go through the vpn, what is at the other end of the tunnel???
A vpn has two points so the story is lacking!!!
