Site to Router VPN?

Let's say we have this:

Site A <----> Router A <----> Router B <----> Site B

There is a VPN tunnel setup between sites A and B through the two respective routers. Router B is port forwarding for a server at site B, and a device at site A is trying to connect to it by connecting to the forwarded port at router B.

Is there a way to ensure this traffic is encrypted by the VPN tunnel between Router A and Router B?

The way IPsec tunnel configuration looks on my routers, you have to assign local sites and that locks in the routing of the encrypted tunnel to go through the routers, but not stop at the edge of them. My routers do not support transport mode, is that what I need?
