Maybe it's just me, but I've found it a PITA to install and configure OpenVPN, in particular because the routing rules on both sides have to cooperate with it (and and firewall rules too, if you need one).
These are many dedicated router/firewall distributions, and some include OpenVPN along with configuration panels for OpenVPN. Hopefully these make it easier to get OpenVPN up and running quickly.
