Help VPN on Android Marshmallow 5.1.1

[VPN]

IOS devices and Windows clients connect with no issue to our corporate firewall using L2TP/IPSec VPN Pre-shared key config.

All my Galaxy Tab4 tablets can't connect whatsoever - they always timeout no matter how long the duration is set.

Anyone been successful with a different app or any insight?
Thanks in advance.

have not been in your situation yet, used to work for a civil government and they had extremely strict VPN rules that would only allow one type of VPN service to make it thru.

a real PITA to set it up.

First thing I can think of, are your Galaxy tablets authorized to connect to the corporate firewall and network as BYOD.

One thing with corporate BYOD, especially if Exchange is involved, is that devices must be fully encrypted, and passworded or PIN'd and satisfy corporate security requirements. Corporate issue devices are often iPhones, and used to be Blackberry. iOS is encrypted by default these days. Huawei are the standard corporate and govt. issue devices in China

If you are doing BYOD, you definitely need to speak to your corporate IT admin, and see exactly what their requirements are, e.g. full storage encryption, and to get the Tabs authorized to connect.

Maybe the problem is the VPN that you're using. I recommend this one: "IPVanish", very reliable and easy to use. Here is a review from the service:

I am now signed up with PureVPN for casual surfing.

don't have a need to sign into a corporate high security server anymore though.
the one I used to use, required 3 levels of passwords just to get inside the main server, then a password to get into each sub-level server. it was a super PITA to work with. Nothing was easy, and only 1 or 2 people had clearance to set it up for you.... out of a corporate user-base in the 10,000 range.....
Wait times for the Help Desk got into the "weeks" range to get things done.
