Help me use my Raspberry Pi to access the remote network which the NVR is on

[Thor187]

Scenario:

Location A: Fiber Internet ( No static IP )
Internal Lan: 192.168.88.1/23

Location B: Fiber Internet ( No static IP )
Internal Lan: 192.169.1.1/23

I would like to be able to browse the internal LAN of Location B from Location A.
( I do not want to port forward every device - I ideally want to tunnel / VPN in from PC on Location A and be able to access the internal Lan of Location B, possible? )

I have a Raspberry PI 3 Model B stationed at Location B that can be used for the VPN?

I am lost on the practical how-to, but conceptionally I think it should work?

Somehow, have the VPN bridge the internal LAN & only port forward the VPN port on the router of Location B
( which should be more secure than exposing the NVR and Cameras directly on the internet via conventional port forwarding? )

Yes you can, if you want to go the vpn route put something like openvpn server on the pi and forward the necessary ports for it. Then you can connect in with openvpn client. In terms of ip addresses you only really need to worry about the receiving side - so location B; as you dont have a static ip, I would probably recommend using a DDNS service, maybe something like no-ip.
That said I will warn you that vpn's can be a pain to get setup correctly and working (as well as securely), depending on what you want to do, just a plain ssh connection might be easier while still getting the job done. (I would recommend using certs though or making sure you use a strong password).

You can use an SSH tunnel to forward devices (IP + port) to specific ports on a PC at location A.

You can try Openport as a reverse SSH service.
Makes it easy and free for a single device.
