For the last decade or so I have been running cheap Asus routers on my home network. They support dyndns and OpenVPN out of the box. I assume that other manufacturers offer the same thing.

I haven't poked around in the guts of their vpn setup. But it's generally password protected and I would assume in the clear. So I replace accounts frequently and only leave it running if I am out of town and have some project I may need access to.

Basically you vpn to yourname.dyndnsprovider.com and you are done.

The rest is DNS Setup which.is sort of up to you but you can easily configure to something like machinename.home.mydomain.net

Microtik routers can also run a VPN just fine. :)
