subject: What You Need To Know About An Iphone Vpn Connection [print this page] An iPhone VPN allows users to connect securely to the Internet and communicate with other people around the world. IPhones enable users to access the Internet by connecting to any wireless network. The popularity of smart phones has resulted in many cafes and coffee shops providing users with free Internet services. Such public places are often the site of a variety of hacker attacks.An iPhone VPN connection is an extremely good idea for users who frequent these public networks.
How an iPhone VPN works
A Virtual Private Networkcreates a tunnel between a device and the Internet. The VPN connection encrypts the information that is passed through the tunnel. If that information is intercepted, it will impossible to decode. Quality iPhone VPN providers also offer NAT Firewall. Nat Firewall is very effective against stopping hackers from accessing devices. Nat Firewall can recognize and block unwanted inbound scans. Hackers employ these scans to take control of a system and install malware or steal information.
iPhone VPN protocols
There are generally three VPN protocols available for users: PPTP (Point to Point Tunneling Protocol), L2TP/IPsec (Layer 2 Tunneling Protocol with IP Security) and OpenVPN. Every modern computer and mobile device supports both PPTP and L2TP/IPsec. However, only Windows, Macintosh and Linux support OpenVPN. Therefore, PPTP and L2TP/IPsec are the options for iPhone users.
PPTP
PPTP allows iPhone VPN users to get basic 128-bit data encryption. This protocol is popular because it provides a high speed connection. It is also very easy to configure and is extremely stable.
When comparing VPN protocols, users should consider whether connection speed or security is more important.Higher data encryption requires more processing power. Thiscan slow down connection speeds. Users who want a fastiPhone VPN should choose PPTP.
L2TP/IPsec
This protocol provides a considerably higher level of data encryption with 256-bits. It also provides an additional type of security called data integrity checking. L2TP/IPsec checks the integrity by encapsulates the data twice. This prevents third parties from intercepting or altering the data while it travels across the Internet. However, this additional security requires more computing resources. This can cause slower connection speeds. For users whose top priority is security on an iPhone VPN, L2TP/IPsec is the best option.
An iPhone VPN connection is essential for users who want to maintain privacy and protect their information. Users who frequently access public Wi-Fi networks should especially consider this option.
