This has frustrated me for a month or so... I can get onto my work VPN via the ShrewSoft client (ike and ike-qtgui) but it's not integrated with NetworkManager (and overwrites /etc/resolv.conf, interfering with it).
You have to resort to manual configuration of the dnsmasq instance created by NetworkManager in order to get it to play nice with managed connections - turn off the DNS settings in the ShrewSoft client and add them manually to dnsmasq to stop it overwriting /etc/resolv.conf The manual config above may also work, but likewise, won't play nice with other NetworkManager connections. The NM plugin for StrongSwan has been updated to support PSK but I don't know if this means it supports IKEv1... it imposes a 20 character minimum, and of course, my network admin has configured a PSK shorter than this, so I can't test it. I agree with the sentiments expressed above that removing support for an exceedingly common (if not best-practice) VPN configuration does not create the best impression of Ubuntu. RedHat has retained support via the NetworkManager-libreswan plugin as described in the page below. https://access.redhat.com/documentation/en- US/Red_Hat_Enterprise_Linux/7/html/Security_Guide/sec- Securing_Virtual_Private_Networks.html Sadly, Debian still has libreswan in the "experimental" section. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1457078 Title: L2TP client support for PSK removed from 15.04/15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-strongswan/+bug/1457078/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
