Route all traffic through Peer to Peer (Shared Key) VPN

Hello! As always thank you for your videos. I saw this, and it really helped me set up my VPN (Custom Built PF Sense at the master site), and a SG-1100 at the remote site.

My question is, is there an easy way to route all of my traffic at the remote site through to the master site via the VPN once connected?

I have tried so many things from Google, but nothing seems to work. Please only if its a quick link, or a quick direction please help.
