I want to connect my home and office computers(atleast share files, full TCP/IP would be best). But the problem is both computers have invalid IPs 172.16.x.x and I do not have control over gateways to
The invalid IP range will not be a problem. Just ensure that they are in different subnets. At least one of the systems will need a static IP address. Run the VPN server on this system. The other system will act as a client.
Yes IPs are static but NOT valid. I think you mean valid and not static. Btw I dont think different subnet is required as far as I can route IP packets to VPN interface. The problem is I dont have control over gateways(who masquerade my packets) so I cannot setup simple forwarding to VPN.

Whats an invalid IP? There is nothing invalid about the RFC 1918 IP blocks. It is just that routers should not carry them out of their internal subnets (Egress filtering is a MUST for these blocks, as against a SHOULD for total egress filtering). If your router is willing to route for these, then they are routable.

This is what you are saying?
RFC 1918 block<----->NATing gateway<----->NATing Gateway<---->RFC 1918 block And you have no control over either NATing gatway. You won't be able to create a VPN unless at least one of your gateways is willing to route your IP block for you. Ask for both static routable IPs (NAT should not be left to your ISP, they have no business doing that, unless they are offering IPV6. That they don't offer you a publically routable IP is an indication that they are cheap).
