I have a server running Leap 15.3, using Wicked for network management. While it’s able to request and assign an IPv4 address fine, for some reason IPv6 refuses to work. Other devices on the network are able to get Ipv6 addresses, so I doubt this is a router issue.
Thing is, it was working fine a few months ago. In the meantime, I changed a few things in my network and I just realized this weekend IPv6 was not working. However, I know it is not because of the switch to 15.3, it was also not working on 15.2 a few days ago.
Here are some command outputs. Let me know what else would be needed for troubleshooting:
