This howto covers setting up an OpenVPN Server for access to your home network as if you were local. It's an excellent alternative to opening a bunch of ports in your firewall and exposing poorly secured programs to the world wide web.
Here's the overview:
- install OpenVPN on laptop to generate keys for server and a few clients
- configure dd-wrt router
- configure clients
Please respond in the Comments what hardware you used this how-to on, and any differences. I will update original article with your input.
