re DynDNS there are other alternatives too, one of the router companies provides it built in, never used it.
I've had good luck with DynDNS so I don't bother.

I still think you don't quite understand something, the VPN device/router whatever creates the doorway for YOUR PC to connect to a DEVICE on the other side. It does not transfer network traffic from the other side through the tunnel to your PC.
You need to connect to something there, a device, a PC something to see the local traffic. (There may be specialized VPN / routers that do this, I've never seen on, but it will not be your normal VPN/Router.

I set up a lot of VPNs, I usually call them remote users. Many of my clients have one or several people that work predominately remote.
I also support most of those clients through the same connection.

For me to manage that VPN router remotely (I turn off remote administration), I have to remote into a server on the inside, and use it to administrate the router itself.

Now here's a fun thing, somewhat unrelated, but think it through.
When I set these up I need to test them, but you can't properly test them from within the network.
So I VPN into my home/office network logging into a desktop there, then I fire up VPN on it back into the client and Remote desktop into another machine at the client.
