unable to access folders and files on NAS via VPN. I can see the NAS but I don't get access to anything on the NAS. Is it a port problem? I need a solution.

I can handshake the router at the NAS location via PPTP VPN and that is as far as I can get. Any further access is not possible. I cannot ping the NAS

I am using SMBI cannot ping NASWindows PPTP VPNI also tried Open VPN with only handshake results

Reads like basic VPN issues - much more but a problem with your undefined NAS, probably an obsolete legacy ReadyNAS, probably a legacy ReadNAS OS 6 system ... who knows. Hard to understand using PPTP, because of the Point-to-Point Tunneling Protocol and GRE have problems with Network Address Translation (NAT), NAT routers use techniques such as PPTP passthrough that allow GRE packets to be mapped to clients - so only if you have a good VPN router in place. Your Internet connection (where you intend to terminate the VPN) does have a public routable IPv4 address, or are you located behind e.g. an ISP deploying Carrier Grade NAT (CGN)? OpenVPN proofs to be much more NAT-friendly, and offers nice readable logs. I don't know what to make out of your "Open VPN with only handshake results".

What router are you using (manufacturer/model)? Is it running open source software, or the manufacturer's?
