L2TP-over-IPSEC on Ubuntu
I expected it to be built-in but L2TP-over-IPSEC support in NetworkManager on Ubuntu 16.4 seems to be unavailable. Turns out it’s available on Launchpad.
$ sudo add-apt-repository ppa:nm-l2tp/network-manager-l2tp $ sudo apt-get update $ sudo apt-get install network-manager-l2tp
The only hitch seems to be that
xl2tpd is running by default but needs to be started and configured on-demand. I disabled it.
$ sudo update-rc.d xl2tpd disable
Now I can start the VPN without issue.
