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

Problem is in kernel vue of routing
ip route get fd99:1234:beef:cafe:fade::7000 from
fd99:1234:beef:cafe:fade::7fff
anycast fd99:1234:beef:cafe:fade::7000 from
fd99:1234:beef:cafe:fade::7fff dev lo table local proto kernel src
fd99:1234:beef:cafe:fade::7fff metric 0 pref medium
After
ip route replace fd99:1234:beef:cafe:fade::7000 from
fd99:1234:beef:cafe:fade::7fff dev wig0 table local
evrything is going back to normal behavior.
Thanks for your support
