Top VPN tools for iOs and how to configure them
When connected to a VPN that is iPhone/iPad as a normal PC. This means that companies need a normal VPN access. This can be a VPN router or a Windows Server. The connection via internal settings on the iPhone/iPad. Manufacturers control how Juniper or Cisco are available in the app store apps for ready connection that simplify the configuration and start the VPN and the traffic.
Different VPN protocols
IPhone/iPad supports Cisco IPSec, L2TP/IPSec and PPTP protocols. This means that you can use each VPN server, which uses these protocols. You can configure the user authentication over MS-ChapV2, RSA SecurID with CryptoCard or a symmetric key (shared secret).
Point-to-point tunnel Protocol (PPTP)-based VPN traffic consists of a TCP connection to TCP port 1723 on the VPN server, to manage the tunnel, and-gekapselten from GRE (generic routing encapsulation) packages for the VPN data. However, PPTP traffic can have problems with firewalls, NATs, and Web proxies. To avoid such difficulties, firewalls must be configured to allow both the TCP connection and GRE-encapsulated data.
PPTP allows encrypted encapsulation of various network protocols. After authentication is performed, a PPTP VPN encrypts the connection. The encryption is based on the password of authentication. More complex the password encryption is better. Since the encryption and the transport of individual IP packets are carried out by the GRE protocol, sure that the hardware firewall or the DSL router that you use supports this Protocol.
Who is a current FritzBox, can configure it as a VPN server that works with iPhone/iPad. For more information visit the website of AVM.
Select VPN using L2TP
The second variant, to build a VPN is the layer 2 tunnel Protocol (L2TP). This Protocol is more secure than PPTP, but for more complex at the facility. L2TP uses IPSec to establish an encryption. Reliably, you can encrypt the traffic, unlike PPTP, already before the authentication in building a VPN with L2TP.
Because L2TP uses IPSec traffic encryption, you can perform even a 3DES encryption with this type of best VPN for ios. The use of an L2TP-based VPN requires a CA infrastructure. You can use also Juniper JUNOS pulse and Cisco AnyConnect.
For these methods, appropriate apps with which you perform the establishment are in the app store. This is easy for even the little experienced users if the connection data of the VPN available.
The client allows the manual configuration, but also the import of profiles with the iPhone/iPad configuration utility. The AnyConnect client configuration is as simple as the configuration with Board means of the iPhone/iPad.
Users enter the data, which tell them the administrators. Certificates can be used for authentication. This is required if you want to use connect-on-demand. In this way, you can route specific requests to resources, for example Exchange mailbox or SharePoint automatically via the VPN.
