How to implement a proxy tunnel between two computers?

Question

Computer networks

The office has a regular computer with Windows 7, which acts as a network storage. Also at office connection with white IP. How can I connect to the office computer so that only the office IP is visible to external resources?

In the know about proxies, but you need some solution based on the entire connection, and not just setting the proxy settings in the browser, because applications will be used where proxy settings in the settings are not possible.

UPD: I will slightly clarify the task, the ultimate goal of which is to use (get) the ip of the office without being in the office itself.

Answer 1

Colleague, you obviously mixed up something. And this is something in the knowledge of addressing technologies and network protocols.
1. At the office, you connect to the smb ball (and it doesn't matter if it's a NAS, Windows server, Linux or etc) through an internal - "gray" IP address, most likely of the form 192.168.XX
2. You have a router that performs the NAT function and most likely DHCP - ie. it 1) distributes addresses within the network for devices from the same range, and also 2) allows these devices to access the Internet, replacing their "gray" addresses on each packet with their "white" issued provider when connecting, i.e.
3. No one outside the network (on the other side of the router) sees your internal addresses (unless inside some protocol - for example smtp - they are not forcibly informed about this), but even if they see them, they will connect "outside" - from the global network - they won't be able to.
Total:
1. either forward the ports you need for SMB out through the router (this is easy to google, but not always easy to configure - it depends on the router model)
2. Or you raise the VPN server - and everyone connects to it and through this tunnel connects to your share through the gray address
3. Either use something like hamache and create a virtual local area network - almost like in option 2, only someone else raised the VPN for you.
