unfortunately it's not working:-( it takes me long time to debug it on my own server and a long discussion in this ticket: https://community.openvpn.net/openvpn/ticket/886 it's not possible to set cipher AES-256-GCM since in this case old clients eg android client which not updated to 2.4.x are not able to connect. -- Levente "Si vis pacem para bellum!" _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org
