[wireguard-dev] Help about configuration

[nicolas prochazka]

Hello, can somebody tells me what I do wrong :
I can ping from server 1 --> client 1  ( ping fd00:14::8b5:8aff:fe85:f3ee ) .
but not from client 1 --> server1  ( ping fd00:14::8b5:8aff:fe85:f3ec )

we can notice
RX packets:230 errors:1112 dropped:0 overruns:0 frame:1112
on server side  seems strange

wireguard : v0.0.20170918]
kernel : 4.9.23 on client1
kernel : 4.4.0 on server 1


Regards,
Nicolas Prochazka
