    Hey guys!!

    I am trying to setup my mobile vpn! Indeed, I already have it working!
    I am using aes256 and sha256, etc my clients are able to connect, no issues

    But now, I needed to make my iOS clients to connect using iphone and Ipad. And no way to put the tunnel up for those guys!

    In a troubleshooting, I changed the hash algorithm to Sha1 and it comes up! I need to change for both phases!

    But for security reasons and policies, I cant leave it working using sha1.

    Did anyone face the same issue? Or anyone having it working with Sha256 or an app that I can use and not using the native iOS vpn setup???

    Thanks in advance,

    Diego

      iOS only supports SHA1 there AFAIK, it's not configurable. You can at least enable multiple options in the P2 so clients that support it will use SHA256.

          iOS 8 does have SHA256 support (and better DH groups), but it can only be accessed by creating a custom profile based on IKEv2 using Apple Configurator. It's about as inconvenient as they could possibly make it.

          And it's iOS 8 only. No OS X support.

            IKEv2 is a better idea in general, though only if all your mobile clients support IKEv2. Apple does indeed make it about as painful as possible to setup IKEv2 on iOS.

                Apple Configurator is an enterprise configuration management tool from Apple. You can find it in the App store.

                But honestly, I encourage you to turn back now…
