My Tumbleweed system does not get a public IPv6 address. The reason is unknown, but it must be a configuration problem, because all other dual boot OS, TW in rescue mode and even the KVM VMs get an IPv6 address on the same hardware. The router is OpenWrt based and seems to work fine. I already tried to copy the network configuration from the rescue system. I use a Wicked based network configuration, set up with YaST. For privacy reasons I replaced some numbers with "xx". # wicked ifstatus br0 br0 up link: #16, state up, mtu 1454 type: bridge, hwaddr xx:xx:xx:xx:xx:xx config: compat:suse:/etc/sysconfig/network/ifcfg-br0 leases: ipv4 dhcp granted leases: ipv6 dhcp requesting addr: ipv4 192.168.xxx.xxx/24 [dhcp] route: ipv4 default via 192.168.xxx.xxx proto dhcp # cat /etc/sysconfig/network/ifcfg-br0 BOOTPROTO='dhcp' STARTMODE='auto' ZONE='home' BRIDGE='yes' BRIDGE_PORTS='eno1' BRIDGE_STP='on' BRIDGE_FORWARDDELAY='2' # ip -6 addr show br0 16: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1454 qdisc noqueue state UP group default qlen 1000 inet6 fe80::406e:b2ff:fe1d:ae7/64 scope link valid_lft forever preferred_lft forever # systemctl status wickedd-dhcp6.service ● wickedd-dhcp6.service - wicked DHCPv6 supplicant service Loaded: loaded (/usr/lib/systemd/system/wickedd-dhcp6.service; enabled; vendor preset: disabled) Active: active (running) since Mon 2021-05-31 11:37:15 CEST; 53min ago Main PID: 26380 (wickedd-dhcp6) Tasks: 1 (limit: 4915) CPU: 48ms CGroup: /system.slice/wickedd-dhcp6.service └─26380 /usr/libexec/wicked/bin/wickedd-dhcp6 --systemd --foreground May 31 11:37:15 mybox systemd[1]: Starting wicked DHCPv6 supplicant service...
