I have managed to setup tls-crypt on my desktop clients, but no luck with iOS.

This is particularly troublesome since I live in a country that has recently become heavy handed in blocking VPN connections. Tunneling OpenVPN over something else is not particularly easy on a non-jailbroken iOS device — so tls-crypt would be really useful for me when mobile, and seems to be working as expected in Linux and macOS.

yes this is unfortunate but Open VPN 2.4 (where tls-crypt has been introduced) is not supported by official Open VPN iOS client yet. I too wish it was.

Try non EC setup with some common port 443 or 21 - depending on your country infrastructure it might work.

Yeah, I've been through all of that. DPI is being implemented and connections are sporadically getting dropped during the key exchange regardless of port number or whether TCP/UDP is being used. tls-crypt seems to be getting around this for the time being.

At home I tunnel OpenVPN over different things, but like I said, that's not so easy with vanilla iOS. So if I'm not at home and want to use something like Skype, there's often not much I can do.

What version of OpenVPN is OpenVPN Connect currently based on?

That's interesting. So it's more a matter of when OpenVPN 3.0 supports tls-crypt — I guess.

Looks like many commercial vpn providers cracked it already as many mention ecc openvpn

So annoying a bit that there is no free version yet. I wonder if maybe one of this commercial clients accepts any ovpn files. I will look around

I would not object to paying for a well-maintained iOS OpenVPN client that's feature compatible with the latest stable OpenVPN release if such a thing exists. An added bonus would be the ability to actually edit ovpn files without having to import them from scratch . . . .

I was wondering if anyone has found a solution to this yet?

@dariusz -- did you find any other commercial vpn that could support this?

I also wouldn't mind paying for a fully compatible version...

Hi all,
Just wondering if there was an update on the support for 2.4 for iOS yet?
or if anyone knows of any commercial based app?

Cheers

We are currently working on an upgrade. It will add support for tls-crypt and will also ship with a new version of mbedTLS, which should make it feature compatible with openvpn-2.4 (although everything should work except for tls-crypt).

Thanks for the update, but this seems contradictory. Will there be tls-crypt support or not?

Sorry, my statement was confusing. The last part of my sentence was referring to the current version.
On the current version I expect everything[tm] to work except for tls-crypt.

In the next release there will be tls-crypt support.

Does it mean that upgrading mbedtls will bring support for elliptic curve crypto? This part does not work with current version.

the new Connect for iOS will most likely ship mbedTLS-2.6.0, thus anything it supports should be supported by the App too.
