Hi,
I am trying to connect remotely to specific devices on a residential LAN. I have an iPhone app that can control these devices if the phone is on the same WiFi network as the wireless devices. If not, the app is unable to find them.

Is there a way to have the phone see the devices on a remote network? (These devices control lighting etc and are not PCs). Is VPN the right solution?

I really want to just connect from one residence to another, so if there was some way to create a dedicated connection between the two such that the LANs were merged, this would work for me.

Please help.

Thanks.

Depends if the app only supports devices on the same network or it actually can control any ip address. If you can put in any ip and it does not need to be on the same lan segment you can likely get it to work with simple routers and port forwarding.

If it actually requires that the device be on the same subnet then its not a simple things to do. You will need a vpn but it is not one supported by most consumer routers. What you need to do is build a layer 2 tunnel as opposed to a layer 3 tunnel which most do. The protocol that is generally used is called L2TP. You would have to see if something like openvpn can do that. You could I guess buy some used cisco commercial routers since they support it.

The target network is remote (it's 30 miles away), so connecting directly via WiFi is not feasible.

Oh. I thought you were talking about relatively local WiFi.

OK...Port forwarding through the target router might work.
