[SOLVED] Failed to connect using ipv6 outside rootless container

Failed to connect using ipv6 outside rootless container

I'am trying to setup my services with rootless docker using default rootlesskit with slirp4netns. Everything works file until my service try to connect using ipv6 to outside service. With curl -6 [<some exising ipv6 address>]:8080 I always have Network is unreachable, in same time connections to same server with ipv4 works fine. I've enabled ipv6 in docker:

{
  "ipv6": true,
  "fixed-cidr-v6": "2001:db8:1::/64",
  "experimental": true,
  "ip6tables": true
}

and enabled ipv6 in rootlesskit with flag --ipv6. What I'm doing wrong? Does rootlesskit with slirp4netns support outside connections via ipv6?

Thanks a lot. Hope someone here can help me after a week of reading manuals...
