Description Stefan Schmid 2017-12-08 15:42:10 UTC

With OpenVPN 2.4 comes support for lz4 as compression algorithm and some Servers need this on Client side to establish a connection.

See "--compress [algorithm]" in OpenVPN-Wiki:
https://community.openvpn.net/openvpn/wiki/Openvpn24ManPage

Please modify the Option-Dialog to make it possible to use it.

Comment 1 Jan Grulich 2017-12-11 12:41:21 UTC

This doesn't seem to be supported yet by NM-OpenVPN plugin, which makes this not possible to implement on our side.

Comment 2 Stefan Schmid 2017-12-11 13:09:45 UTC

I found this RFE on Buzilla from GNOME:
https://bugzilla.gnome.org/show_bug.cgi?id=777768

But since 2017-05-12 no activitiy, what now?

Comment 3 Anon 2019-01-05 10:15:13 UTC

Hello,

NM-OpenVPN does support lz4 now. https://gitlab.gnome.org/GNOME/NetworkManager-openvpn/merge_requests/4

Any chance to have this implemented in Plasma Network Manager ?

Comment 4 Damian 2019-02-20 13:16:49 UTC

I can not import opvn config file when its containing "compress lz4-v2" attribute.
