Encrypt all the things!

I used an Asus RT-N66U router:

I run this firmware:

Which is basically the stock firmware plus OpenVPN support. So all of the other interfaces and stuff are exactly as you find in Asus's help site and documentation.

I get about 80% of my network speed using that config. Before I switched to this router I only got just over 10mbps regardless of network speed.

That's just a bundle of OpenVPN plus the config files to make it easier. It is possible to configure it yourself, or you can just use their bundle.

Hmmm interesting. I'm also tempted with just getting a beagleboard and sticking it between WAN + Router. 1Ghz should be fine for a perm vpn tunnel. Will have to look into this more tbh
