If someone can't launch one app (OpenVPN), how can that same person be expected to launch a different app?
Setting up your VPN initially will require your effort and some expertise from here or elsewhere. I didn't know any of this stuff until I wanted to set this up for my system, and I found the help I needed here.
Using it once it's all set up is a piece of cake. I set this up on my wife's phone, and although she has no idea of the steps I used to set it up for her, she can use the system easily, and loves it.
We literally tap the OpenVPN icon, tap the "On" switch, and that's it.
Two taps, and I'm in!
If your users can't do that, I'm sure they can't operate the BI app, UI3, their email, any web browser, make calls, text, take pictures, etc. So presumably, they have no use for a smartphone at all.
Seriously. This is super easy. It's not even close to being as complex as surfing the net with a web browser, checking my email, texting, or even answering a call on the phone itself!
For YOU, setting it up initially, you will likely want to follow one of the step by step guides, or read the
Wiki here, etc. You can ask for help here, and get it done. There's a bit to it, but there's a lot of help available here.
And once you set it up on your router, and then on your wife's phone, that's it for anything technical.
Once set up, tapping an icon and then a button in that app is all you do to turn on the VPN. At that point, your phone is securely (via an encrypted tunnel) connected to your home network as if you were right there, at home, connected to your home WiFi.
It doesn't matter if you're on someone's WiFi, or out and about on your phone provider's cellular network. You're now securely "inside" of your home network.
Everything after that is exactly as it is when you're home. The Virtual Private Network gets you into your home network as if you were right there. It's very handy.
Then, when you want to shut off the VPN, you just open the app and click on that same "ON-OFF" switch, and you're disconnected. It's that easy.
It's not as hard as 99% of the typical tasks everyone does all of the time on their smartphone.
Two clicks. Two!
She can handle it. And you'll both love it for other uses than accessing BI. How cool is it to make two clicks, no matter where you are, and have your phone then behave as if you were home on your own wifi?
Further, setting things up right, so your cameras cannot access the internet, and you aren't forwarding any ports is highly recommend from a security aspect.
It's worth considering seriously.
