I got it.
1. you can't use ipv6 IP from the range of /64 (or other) that you
connect to. As workaround, I build an ULA/64 network to connect both
ends using one ipv6 from the /64 range of the server to connect
2. once the tunnel is up nothing is shown on wg show until first packet
arrive. If you try to ping from server to client -which was my case- you
get an error destination address has to be specified. But as soon as the
client has send a packet (ping or keepalive), tunnel is open both ways
3. the MTU I have to use is 1436
Thanks all for your help.
