I manage a small-office network but have very little actual networking knowledge / understanding.
The network has a consumer grade wifi router (Netgear DG834G), several PCs/Macs, some iPads connected via Wifi, and a couple of file servers (also consumer-grade Netgear ReadyNAS boxes)
I have setup a VPN between one PC (WinXP) on our network and a distant VPS box (AWS EC2), with openVPN; I use the VPN connection in order to have a US-based IP address (since I'm not in the US).
Here's what I would like to do: I would like to be able to use the VPN from the other machines on the network, including the Wifi connected ones (iPads), without setting up a VPN client on each machine.
I think I need to either have one machine setup as a gateway that the other machines would use, or maybe connect another router that would act as both a gateway and a VPN client, that one could choose to connect to in order to go through the VPN tunnel? Or am I looking for a proxy?
(I'm a little confused, sorry if the above is unclear).
What's the simplest way to achieve that? There must already be tutorials describing what I want to do, but I can't seem to find any after numerous Google searches...
