Need help with VPN IPsec

Dears Please any replay ??

You should look at the Personal VPN feature of NEVPNManager, which lets you programmatically configure IPsec VPN (subject to the user’s approval, of course).

Hi Dear

thank you for the replay but is there any examples about that ??? becuse i didnt find the group name

Please i need answer for this quastion

Regards

Khaled Abdullah

is there any examples about that ?

There’s no official sample code for this but I expect you’ll find a bunch of unofficial code for it out there on the ’net.

I generally recommend that you start this process by creating a configuration profile for your VPN setup. You can do this using Apple Configurator. Once you have a configuration profile up and running, it’s a relatively straightforward job converting that to NEVPNManager code. If you get stuck with that part, I’d be happy to help.

That’s usually caused by an authentication failure, meaning you haven’t set up the user’s credentials properly. Make sure you:

• Set

  useExtendedAuthentication

  to true

• Set

  username

  to the account name

• Set

  passwordReference

  to reference the user’s password in your keychain

This last part is a bit tricky. Pasted in below is the code I use for it.
