VPN connection over L2TP/IPSec with pre-shared key won't work

My VPN connection over L2TP/IPSec with pre-shared key won't work with my z4 tablet. 

 

After a few seconds vpn is disconnected. I tried the same with pptp and it works, but that isn't what i want.

 

My Draytek Router has no request with L2TP in the logs.

 

The connection works without problems with i-phone, LG and Samsung Smartphones, all with the newest software.

 

Is there way to fix this problem? Thanks in advance!

Hi,

 

It seems Draytek provides their own app for this. What if you download this app and try to connect using it: https://play.google.com/store/apps/details?id=com.draytek.smartvpn

Check the very last option. L2TP/IPsec with 96 bit key. It was added recently and fixes issue with Synology VPN.

Also make sure PSK key is 8 lowercase alpha letters, no special characters. I didn't manage to make it work on vanilla Android too.

Best regards,
