VPN IPSec Advanced Settings Phase1 Phase2 Algorithms
2. Please input the detailed description of your suggestion or problem
In Ubuntu 17.04, it's possible to enter in Network Manager .. L2TP IPsec Options ... Advanced ... a Phase1 Algorithm and Phase2 Algorithm. This is shown in one of the attached images. I have resolved this issue at https://ingbrief.wordpress.com/2017/10/14/ubuntu-l2tp-vpn/ .
In Deepin, there are no fields for advanced settings. See the other attached image.
3. Problem reproduce frequency
Without setting the Phase1 Algorithms and Phase2 Algorithms, Deepin Linux cannot connect to a IPSec tunnel to an L2TP host. This works on Ubuntu 17.04
