>From the logs, it definitely isn't using IPsec XAuth. The "NO_PROPOSAL_CHOSEN error" means your VPN server is using a legacy encryption algorithm that strongswan considers broken as it is old and weak, it is most likely 3DES :
https://wiki.strongswan.org/projects/strongswan/wiki/IKEv1CipherSuites It would be best if the VPN server can be updated to use stronger cipher suites, but if you can't, in the README.md file, see the "User specified IPsec IKEv1 cipher suites" section : https://github.com/nm-l2tp/network-manager-l2tp#user-specified-ipsec- ikev1-cipher-suites Extract : If you are using strongSwan with this VPN plugin and you need to use the same ciphers that older versions of strongSwan and this VPN plugin used, enter the following in the corresponding IPsec configuration dialog text boxes: Phase1 Algorithms : aes128-sha1-modp2048,3des-sha1-modp1536,3des-sha1-modp1024 Phase2 Algorithms : aes128-sha1,3des-sha1 If you then get a xl2tpd failure, you might also need to stop the system xl2tpd service, see "Issue with not stopping system xl2tpd service" section in the README.md file : https://github.com/nm-l2tp/network-manager-l2tp#issue-with-not-stopping- system-xl2tpd-service I think OpenSUSE doesn't start the system xl2tpd service by default, but Ubuntu does. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1726135 Title: need to use group name To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-l2tp/+bug/1726135/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
