here a company that will provide a free vpn based on open vpn
the free account is here
you can download a Ca and conf file from there and give your open vpn a whirll before trying to get your companys one running, all that is needed after download is to unzip and go to
for import just navagate to where you unziped the files and point to the config file.
not exactlly what you want but the best why to learn is to do, right.
after you get it working you can check the config file and see what sould be changed to get your companys vpn running.
maybe you have some issue with selinux, might have to disable it. in it's confi file set to permissive if it comes up as all the other suggestions don't really work, but maybe not, good luck!
