Our company want to setup VPN sever service on Centos 6 which need to support both SSL and L2TP/PPTP protocols.<br />
SSL is for notebooks or home computer which can use Internet Explorer to connect to VPN server directly. No need to install additional client software. No need administrative privileges to run the VPN client, power user right is good enough.<br />
<br />
And L2TP/PPTP is for iPhone and Andriod phone (No JailBreak or root) to connnect to VPN server.<br />
<br />
Is there any free VPN server good for our environment?<br />
Thank you.

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
