 **Android 6 (Marshmallow) users**: After install, edit `/etc/ipsec.conf` and append `,aes256-sha2_256` to both `ike=` and `phase2alg=`. Then <a href="https://libreswan.org/wiki/FAQ#Android_6.0_connection_comes_up_but_no_packet_flow" target="_blank">add a new line</a> `sha2-truncbug=yes`. Indent lines with two spaces. Finally, run `service ipsec restart`.
