VPN client for Ubuntu 16.04

[tzah]

Hi Guys 

Does anyone have an installation guide for Ubuntu 16.04 that I can send my users to self-installations? 

On the official guide is Ubuntu 12

Thnk you !!!

I have not tested it, but this guide looks promising.

This looks very promising - and easier.

I did this and it works for me:

1. Install network-manager-l2tp:  sudo add-apt-repository ppa:nm-l2tp/network-manager-l2tp and sudo apt-get update sudo apt-get install network-manager-l2tp
2. If using gnome, install the gnome plugin (if using another desktop environment, see if there's a plugin for its network manager): sudo apt-get install network-manager-l2tp-gnome
3. Reboot
4. Navigate to Settings > Network > Click the +button > Select "Layer 2 Tunneling Protocol (L2TP)"
5. Name the new VPN connection something
6. Put the host name or address in the Gateway field.
7. Put username in the Username field.
8. Click the icon in the Password field and select your preference for how to supply the password.
9. Click IPSec Settings...
10. Click the box for "Enable IPsec tunnel to L2TP host"
11. Enter the shared secret into the Pre-shared key field.
12. Leave the Gateway ID field empty.
13. Expand the Advanced options area
14. Enter "3des-sha1-modp1024" into the Phase 1 Algorithms box.
15. Enter "3des-sha1" into the Phase 2 Algorithms box.
16. Leave the box checked for "Enforce UDP encapsulation".
17. Click OK.
18. Click Save.
19. Open a terminal and enter the following commands to permanently disable the xl2tpdservice:  sudo service xl2tpd stop
20. Also enter the following:  sudo systemctl disable xl2tpd
21. Open Network Settings and try to turn the VPN on.

No one should be using 3des for anything new.  Does aes128 work instead?

I believe you can call in and request AES - I'm gonna have to do this so I can get a VPN node in my datacenter rack....

[PhilipDAth]

AES is available by default.  You don't need to do anything.

[BadOscar]

Good deal - I haven't tested with linux / mac yet but it's full on awesome with AD - all the information for using an l2tpd client show 3des - I had to call in to get some features enabled for I believe some wireless or maybe a firewall setting so it would not surprise me if the same had to happen for AES.
