Public bug reported: [Description]
When setting up a sit tunnel (with Hurricane Electric for example), one can use a netplan config like (https://netplan.io/examples#connecting- an-ip-tunnel) this: network: version: 2 ethernets: eth0: addresses: - 1.1.1.1/24 - "2001:cafe:face::1/64" gateway4: 1.1.1.254 tunnels: he-ipv6: mode: sit remote: 2.2.2.2 local: 1.1.1.1 addresses: - "2001:dead:beef::2/64 gateway6: "2001:dead:beef::1" This works well with a static IPv4 on eth0. Had eth0 been configured by DHCP one would be tempted to omit the 'local' param and let the network stack figure out which one to use to reach the remote endpoint. This used to work that way with ifupdown but netplan complains: Error in network definition: he-ipv6: missing 'local' property for tunnel mode: sit ^ [Additional information] # lsb_release -rd Description: Ubuntu 18.04.2 LTS Release: 18.04 # apt-cache policy netplan.io netplan.io: Installed: 0.97-0ubuntu1~18.04.1 Candidate: 0.97-0ubuntu1~18.04.1 Version table: *** 0.97-0ubuntu1~18.04.1 500 500 http://archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 100 /var/lib/dpkg/status 0.40.1~18.04.4 500 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages 0.36.1 500 500 http://archive.ubuntu.com/ubuntu bionic/main amd64 Packages ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: netplan (not installed) ProcVersionSignature: Ubuntu 4.15.0-51.55-generic 4.15.18 Uname: Linux 4.15.0-51-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.9-0ubuntu7.6 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Tue Jun 11 16:26:25 2019 InstallationDate: Installed on 2018-07-15 (331 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180714) ProcEnviron: LANG=en_CA.UTF-8 TERM=xterm-256color SHELL=/bin/bash XDG_RUNTIME_DIR=<set> PATH=(custom, no user) SourcePackage: plan UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: netplan.io (Ubuntu) Importance: Medium Status: Confirmed ** Tags: amd64 apport-bug bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832404 Title: sit tunnel should not require the local param To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1832404/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
