OpenVPN Compatibility?

Adding my name to the list - iPhone, iPod Touch and iPad OpenVPN support would be amazingly useful for me.

I want OpenVPN too !!!!!!!!!!!!

Unfortnally, it's very unlikely to see an official OpenVPN support on iPhone/iPod/iPad.

For proper use, OpenVPN require external command line execution (configuration of IP, route settings, DNS push, etc...), which would represent a "security issue" from Apple.

The only solutions that exist are under unofficial ways.
I can't post any links here, but Google is your friend 🙂

Now with the Filemaker app on the IPAD I could connect my whole salesforce to their files if I only HAD OPENVPN!!!!

+1 for openvpn.

I would like to see Apple provide OpenVPN SSL support in iOS.

I keep hoping to see OPENVPN for the IPAD. PLEASE!!!!!!!!!!

GuizmOVPN, some questions:

1) Why does OpenVPN require command line execution for configuration settings?

2) How does Juniper's Junos Pulse SSL VPN app work differently, so that it can work on an iOS device? What about Cisco's AnyConnect SSL VPN app?

3) Since these other SSL VPN apps are actually there on the App Store, and apparently work, why not OpenVPN? You imply that there are technical reasons for OpenVPN's absence, rather than simply a lack of some developer creating an OpenVPN app.

I'm just trying to understand "why" because it simply doesn't make sense to me.

I believe it's because OpenVPN uses a tun/tap device.

I hear someone has done it via emulation using the iPhone's ppp device.

Haven't tried it myself but here's the link for what it's worth.

I have to ask "why" nobody has compiled the kernel modules from the TUNTAP project into the iPhone's kernel. Is there no open source for it? If not, I believe you would have to reverse engineer the kernel to inject a module into it.

Perhaps if someone wishes to donate to Mattias Nissler, the creator of TUNTAP, he may feel obliged to port it over to the iPhone kernel. 🙂

Sorry to answer so late, I didn't see your message.

1) OpenVPN is using external applications (route, ifconfig, ...) to set up the requested system routes, IP address and DNS. There should be a way to change that to use other APIs, but they actually don't exist or are not "public".

2) Juniper and Cisco have access to a VPN/SSL API added in iOS4.1, which is not opened to other developers.

3) The reason why OpenVPN is not on the AppStore is not a lack of some developer, I'm really willing to do so, that would make my life so much easyier than trying to find alternative and undocumented ways to interact with the system.

I tryied to contact Apple several times to get access to this VPN/SSL API but I didn't get any "real" answer yet.
I don't know if it's a financial problem (licence), an exclusive agreement they had with Cisco and Juniper, or a lack of interest from Apple to bring "Officialy" OpenVPN on their platform.

PS : If some Apple staff read this message and can give me answers, please do ! 😉

Yes you are right.
OpenVPN uses a TUN/TAP kernel module, that doesn't exist on iOS.
The TUN/TAP driver is opensource, but the iOS kernel isn't, and there is no SDK to develop kernel modules.

The only way is to use a TUN emulation over PPP (made by Friedrich Shoeller), or the VPN/SSL API when/if it'll be accessible.

Just wanted to add my voice to those wanting OpenVPN on iPhone/iPad. The company I work for uses OpenVPN and it would be incredibly useful to be able to vpn in on my iPhone or iPad without hauling my computer around. Most of the stuff I need is just looking at files or console access to our servers anyway, a laptop is overkill. Also it would be great if our sales people could vpn in for access to customer data and product info.

Yet another person interested in official OpenVPN client support on the iPhone / iPad. I've used GuizmOVPN before... it works great! (Thanks Guizmo!) I too work in IT, and would have great utility for informing my employees that they could connect to our OpenVPN server, but of course am not about to suggest (or support) jailbreaking their work phones

we would appreciate openvpn support in the iphone as all of our employees have one and we use apple hardware for most parts (except the server for important reasons though)

Add another paying customers +1 to this request.

The resources needed to add openvpn compatibility would be miniscule and add another avenue of compatibility that no other smartphone has.
