Creating A wireless network: VPN ?

[kaddar]

Greetings, I was wondering something:

I am creating a wireless point to point network, with devices at each node. I'd like to access these devices from the outside internet. Currently, to do that I give each device and wireless access point a static ip, and it works fine.

But I'd like a system where I don't need hundred of Internet static addresses to manage it. I want all addresses to be assigned to a local network, and then to access that network I would connect to it remotely through some sort of virtual private network.

Some sites are not on the same contiguous link. And some sites are not merely PCs, they are either cameras or VOIP nodes that communicate with each other across the internet. So not all clients are computers, therefore I can't simply install software on each client, so it looks like I can't neccessarily use a free solution like OpenVPN?

Does anyone have any ideas about what sort of hardware I should look into for this?

It might be easier just to port forward RDP and use remote desktop.
That'll give you access to a computer at each site and you can use it to manage devices on that subnet.

Hmm, yeah, good idea, that would be easier if they were all contiguous, and I might be able to set it up for the majority of the nodes since a majority of nodes are on a single subnet.

But a couple of nodes were out of wireless range, and ended up on a separate subnet that links over the internet, so there's gotta be some way to bridge the two subnets into one subnet so the VOIP devices can communicate between them.
