In iOS settings, there are options to create a VPN configuration using IPSec, IKEv2, and L2TP. Using the NetworkExtension framework from Apple there's an option to create VPN using IPSec and IKEv2 protocols only. They do work but problem is that I need to create a connection via L2TP since that's only supported by the company's firewall.
There's a question iOS app with custom VPN connect from 2014 and it's answered with:
If you want to connect programmatically in ios 8 you can use only IPSec or IKEv2 protocols. L2TP and PPTP protocols are private for apple. It is not possible to use L2TP and PPTP APIs in your applications. Only Apple is currently using these APIs.
Is there any way to create a L2TP VPN connection from an iOS application (Swift)?
The Personal VPN feature that allows using built-in protocols doesn't support unencrypted protocols, presumably for security reasons:
Personal VPN only supports recommended VPN protocols; it doesn’t support legacy VPN protocols, like PPTP and L2TP.
However, that's not the only way to implement a VPN app. You can also create a Packet Tunnel Provider to tunnel layer 3 packets yourself, or an App Proxy Provider for TCP and UDP connections. A packet tunnel provider would allow using your own L2TP implementation.
This might be solving the wrong problem, though. If this is for a specific company, why not use MDM instead of a custom app? MDM does support L2TP.
It is not possible to create a L2TP VPN connection from an iOS application. Only Apple is currently using the L2TP and PPTP APIs.
Is it possible that the company this is for has some sort of internal framework or package you can use for their VPN authentication within your app?
You can make use of every proxy app available on Android playstore. Basically youre iOS device will make use of the hostpot from android phone.
Remember youre android phone must be connected to L2TP VPN.
Every proxy will put all the connection of VPN shared to iOS device.
iOS device in settings we need to add ip and port. You will now be connected to VPN on iOS.
You can try hosting an l2tp server on your mac and connect another device remotely to the server using the settings->network->vpn->l2tp and provide the settings. I haven't tried it personally. On the iPhone General->VPN Management->L2tp can be used.

Currently Personal iOS Vpn Application implemented using IKEv2 protocol and network extension api but i want implement same thing using Network extension with packet Tunnel provider in tunnel mode.
So can explain clear architecture how to implement and what are library need?
I suggest you look through (and built) the SimpleTunnel sample code. It shows how basic Packet Tunnel and App Proxy providers are set up.
I have an iOS application with a tableview which I would like to send text strings via USB to my Windows computer indicating which cell was selected by the user.Anyone have experience with this type of interface?
I've written a blog post detailing how to achieve this here.
http://thecodewash.blogspot.com/2017/05/communicating-with-your-ios-app-over.html
To answer your question (so this answer isn't just a link), yes it definitely is possible to achieve this utilizing the USB Multiplexing Daemon (usbmuxd) program that is usually installed as part of iTunes. This program can create a socket connection to your iOS device through the USB cable, and allow you to communicate via that socket connection like you would any other socket. The link goes into much more detail.
Hope this helps!
(In short) Yes, you can communicate with ios application via normal socket communication by using ITunes which acts like proxy. In this model your ios app acts like server listening for connection. Windows app must connect to iTunes on port 27015 and estabilish connection to specific port (used by ios app) on connected via usb device. This is done by using a special MUX protocol described here
I want to create a pptp Vpn connection programmatically in Ios 8. I followed this link. By the help of this link i am able to create an IPSec Vpn connection in ios.
But i need to create a pptp vpn connection if any one know about it then please help me how to do it i am very stuck in it.
As far as I know, there is no pptp api support in iOS (currently 9.3.4). The only supported protocols are
IKEv1 (IPSec)
IKEv2 (AES and certificates)
To use these, have a look at NEVPNManager and NEVPNProtocolIPSec class reference.
There's also a good example here:
http://ramezanpour.net/post/2014/08/03/configure-and-manage-vpn-connections-programmatically-in-ios-8/
If you really want to to have pptp, then you have to write your own extension, using the Network Extension framework and for that you need a special entitlement from apple, i.e. you have to write them an email and explain why you need this right.
Cheers
Looking at VPN configuration in apple's Configurator tool, it offers many different types of VPN, such as
L2TP
PPTP
Cisco AnyConnect
Juniper SSL
Check Point Mobile VPN
etc
I'd like to create a custom VPN configuration programmatically using NEVPNManager, however looking at the list of objects added in the NetworkExtension framework there are only 2 protocol classes - NEVPNProtocolIPSec and NEVPNProtocolIKEv2.
I'm new to the world of VPN's, so my question is this:
Are those proprietary VPN types (such as Cisco AnyConnect) just variations of IPSec or IKEv2, and thus can I set them up using one of those protocol classes, or is it not currently possible to do this with NEVPNManager
You can implement your own version of VPN via NEVPNManager, but you can't use it to set up / edit other VPNs (such as Cisco).
Thank you for requesting information about the Network Extension framework. Please note that as of November 10, 2016 this process is not required for developers who wish to use App Proxy, Content Filter, or Packet Tunnel APIs. To use these services please navigate to your Developer Account at https://developer.apple.com/account/ and select the Network Extension capability for the App ID you will be using for your app.
If you are requesting an entitlement for Hotspot Helper APIs and have already filled out the request questionnaire then your request will be addressed at our earliest convenience. Otherwise please visit https://developer.apple.com/contact/network-extension/ and enter the required information.

I've recently noticed that some iOS applications, such as the Astrill VPN Client, are able to create and dial VPN connections. In this specific case they seem to be Cisco IPSEC connections. I have not been able to locate any official Apple documentation on how to do this. Can anyone please tell me how this is possible?
Please note that I know how to configure VPN connections manually. The reason I want my application to do it is to provide an idiot proof and streamlined process for customers.
These iOS apps achieve this by installing a VPN dialling profile that contains a VPN On Demand setting for a specific network and then simply try to connect to an address on that network, which prompts iOS to establish the VPN connection.
VPN On Demand can only be enabled for the IPSec (Cisco) connection type. You can create a dialling profile to do this using the iPhone Configuration Utility to see how it works.
