Ok thanks, well I hadn't heard of that software for the router before, so looks like ive got a bit more reading to do

So I guess the server version of openVPN goes on the router and the client on the remote devices....its a win-win as there is a "openVPN" client for N900 in the repos if memory serves...

...I'll probably need high speeds than those, but I guess there must be an updated router that is compatible. Thanks again.
