I think you've missed the point of how and why you use dynamic DNS.  You 
register the NAT router's public address, not your PC private address. 
Many routers can be configured to do this automatically and do the 
necessary update whenever their DCHP-assigned address changes.  Then you 
configure the router to port-forward to the desired private address and 
you can reach it over the internet by DNS name even though the public 
address may change periodically.   But I don't think you mentioned 
whether you control the router at the remote location or not - and I'd 
probably trust an openvpn connection started outbound with keep-alives 
more than someone else's dynamic dns service anyway.
