Hi, You'll find a comprehensive guide on the Arch wiki (https://wiki.archlinux.org/index.php/OpenVPN). Please read first the setup of the PKI, then read further how to setup a VPN environment. I particular like this howto, because it survived the recent security holes of OpenSSL. But this is just one solution and there are many more, like Ipsec. The article mentioned above should be fine for your case In regards, Maikel > Hi All, > > I have running centos 6 server in my head quarters and branch offices. > > I need to access file server files in both location using VPN. > > How to setup vpn server in both location and how to access it. > > Could any one help me. >
