OpenVPN iOS "Always On" - OpenVPN Support Forum (2024)

I am having a little trouble. Recently I bought an ASUS router which has the OpenVPN built into it. I have setup the VPN server and installed the OpenVPN app on my iPhone and I would like to be able to force my household to use the VPN when outside of the house for security and filtering. It works... Sort of.

They currently can turn off the VPN and it shuts off here and there. I read the iPhone had an always on VPN option but I don't not see anything. Can any of you assist or ran into anything similar?

That "AlwaysOn" feature in iOS doesn't apply to OpenVPN.

You can achieve similar with OnDemand VPN. Google may help with you on details.

OpenVPN does support iOS VPN-on-demand. See the FAQ:

Hi James, thanks for your quick reply. On-demand is very useful indeed but for scenario's where a constant data stream is needed on iOS, it is not enough. When the device goes into sleep mode the connection is reset after 30 secs. When the device becomes active again the on-demand kicks in and there is connection again. Is a real "always on" function something you guys could get to work on iOS in cooperation with Apple? Or are you even planning to do so? Cheers!

The "Seamless Tunnel" setting is as close as we can get to being "Always on". Anything beyond that would need support from Apple in the iOS VPN API.

I use OoenVPN to access my home network and Cisco AnyConnect to access my work network. Both work GREAT from my iPhone (6s+/IOS10) and Surface Book (Windows 10).

On my Surface when I use either OpenVPN or AnyConnect the tunnels stay up basically forever - even if there aren't any packets traversing the tunnels. Only time they go down is when I shutdown or hibernate my PC or the PCs Internet connection breaks.

On my iPhone if I make an AnyConnect tunnel to work it stays up forever. Even if no apps are using the tunnel AND I can lock my iPhone and AnyConnect keeps the tunnel up in the background. It works EXACTLY like it does on my laptop. In fact AnyConnect has stayed connected over night with no issues!!

BUT - OpenVPN disconnects the tunnel Within 30 seconds of my phone locking. I can't find any settings that will make my OpenVPN Tunnel persistent.

So my question is this - IF Cisco can make their tunnel persistent while living under Apples rules - why can't OpenVPN work the same way ??

The answer is weird rules set by Apple.

Are there any updates on this? Especially with WhatsApp Web and similar things using a lot of data in the background, this is rather annoying since my VPN misses all of these connections.

I think it’s impossible to find a better solution here than how it works in connection with iOS 12. If you correctly setup an on-demand connection, then it works just fine and all your traffic is sent via a VPN tunnel, except... everything that uses Apple’s services. Means, Apple built in a bypass function to prevent such traffic like Push notifications, iMessages, FaceTime calls etc. being sent through a VPN tunnel.

However I faced a really annoying behavior of the OpenVPN Connect App in connection with iOS 13 and VPN-on-demand profiles, where even in standby a VPN tunnel is established. Believe me, a kind of always-on VPN is really the worst solution ever that you can imagine on a mobile device. The battery is drained within some (about 8-10) hours, even if you are almost not using your iPhone during that time.

I can only hope that the latest update with the “Battery Saver” feature can fix this issue, otherwise it’s really annoying to charge the iPhone twice a day.
