SmartDNS - Solution for CentOS

Hi all Experts,

I see a lot of VPN providers now offering SmartDNS solutions, specifically to support SmartTVs which require access to services which are block by geoblock location tags and this is something I would also like to setup in parallel to the PPTP / L2TP/IPSEC, OpenVPN Servers I'm currently running today.

What Software in CentOS would I need to install in order to get this working?

Is there anything I can purchase to provide this as solution to complement my current VPN Services.?

What is SmartDNS:  (This is what we Required)
"Smart DNS is a service which differs from VPN's in that network traffic is not all tunnelled to the remote network. Only traffic required for determining your geographical location are re-routed, which does not include normal Internet usage, nor the video stream itself. The advantages are far higher internet speeds, allowing high quality video streams to play from further afield and the ability to access content independent of which country it originates. You don't need to connect through a VPN and it is easier to set up on devices which are otherwise problematic, such as Smart TVs and many set-top boxes."

Many Thanks
Nev

Smart DNS is made just for unblocking web sites. It does not offer IP hiding and encryption. [1] You need to enter the new DNS addresses your smart DNS provider has given you to your Centos resolver IP [2]. There is a how to for other os[3]. Overall better to engage the support of the provider [4] to make sure the setting and have trial before committing

also if you have vpn running and split tunnel is disabled, traffic will all go through the tunnel including DNS traffic. Meaning the use any resources (inc DNS) of the remote network. Processes outside the VPN tunnel use still your local network's resources (inc DNS, i.e. SmartDNS or OpenDNS)

You may want to read these as worth in general for using external DNS service with VPN
