On older kernels, we don't successfully disable LLv6: https://git.zx2c4.com/WireGuard/tree/src/compat/compat.h#n583 There's probably a way to backport that tweak to before 3.17, but I haven't spent time on it. Feel free to send a patch, and if it's clean and fits entirely into compat.h, I'll gladly apply it. _______________________________________________ WireGuard mailing list WireGuard@lists.zx2c4.com https://lists.zx2c4.com/mailman/listinfo/wireguard
