Gerben,
I "think" we figured out the problem. A bunch of us on the podman team
started hacking on it (thanks to Matt, Nalin, Matt, Brent, etc). I think we
have a work around for now. We're still determining the longer term
solution. I commented in the Stackoverflow, but copying here for ease:
=========================================================================================
I just tried this on RHEL 8 and I was able to reproduce this issue. We also
figured out the issue (I think). Try the following:
sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"
You might be being limited by the group range and /etc/subuid /etc/subgid:
https://man7.org/linux/man-pages/man7/icmp.7.html
I'm not sure what the long term solution is yet, but if this works, you can
likely fix it with sysctl for now.
=========================================================================================
Best Regards
Scott M

to have is both internal, i.e. container to container, and external, e.g.
ping 8.8.8.8, inside a single container. I get internal working as well as
external, however never both at the same time within a single container. I
have raised this question on stackoverflow as well. The question on
