In your case, you need to use vpn policy.
First, you need to connect AR750 WAN port to your MOFI LAN and use it as common router. Setup vpn on it.
Then, you should add in the vpn policy, do not use VPN when connecting to your Apple TV.
Your mac mini will still behind NAT of AR750 so I am not sure if SMB works. But you can try.
