Hi, I'm using podman 2.2.1 rootless with slirp4netns and IPv6 enabled (--network slirp4netns:enable_ipv6=true). Straight after starting my container the code inside tries to connect to a server using IPv6 but fails due to the network being unreachable. However if I add a small delay before trying to connect it works. If I use IPv4 this seems to work right after the container is started, which of course still takes a few ms until the code is started. I can actually easily recreate the using podman 3.1.2 as well. this works: podman run -it --network slirp4netns:enable_ipv6=true --entrypoint bash fedora:34 -c "curl -v -4 https://www.google.com" this fails: podman run -it --network slirp4netns:enable_ipv6=true --entrypoint bash fedora:34 -c "curl -v -6 https://www.google.com" but works with a delay: podman run -it --network slirp4netns:enable_ipv6=true --entrypoint bash fedora:34 -c "sleep 2; curl -v -6 https://www.google.com" Is the network setup done after the container is already started and thus this needs to be expected? thanks, Hendrik
