Hi all,

I use wireguard between 2 Debian11 and face a problem: traffic goes in 
to wireguard interface/ip address but goes out with lo as interface with 
the right ip address

19:23:50.287492 wig0 In IP6 fd99:1234:beef:cafe:fade::7000 > 
fd99:1234:beef:cafe:fade::7fff: ICMP6, echo request, id 18272, seq 5, 
length 64

19:23:50.287509 lo In IP6 fd99:1234:beef:cafe:fade::7fff > 
fd99:1234:beef:cafe:fade::7000: ICMP6, echo reply, id 18272, seq 5, 
length 64

Any clue on this ?

Thanks for your support

Daniel
