       @fluepke You're doing it wrong.It should be like this:Client: sends any kind of packet to the server over IPv4Server: respons with ICMP Connection Upgrade, with a list of global unicast IPv6 addresses, and the header of the packet that prompted this, then continues to process the packet as normal
