For quick and dirty connections out, I use PuTTY to Set up a dynamic local SSH tunnel to a host of mine on the Internet. Then I use the tunnel as a SOCKS proxy. It's fairly straightforward to set up.
For remote access and Internet access over wifi for non-SOCKSable stuff I use Strongswan. I have a small scale darknet set up with it (just me and a few friends) so it's already there for me, but I wouldn't recommend it unless you know your stuff.
