hi ,

i can’t ping outside from my lxc container. (lxc 5.15)

ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

“ip a” cmd result inside container:

ip a

“ip r” result :

ip r

I would really appreciate any help.

Thanks so much in advance

That’s a LXD question and LXD is no longer part of LinuxContainers.
See https://linuxcontainers.org/lxd

In this particular case, I’d recommend going through the part of the LXD doc which covers potential interactions with firewalld or Docker as it looks like you’re being firewalled off by something.
