Please provide the the reuested information from the template, in particular what version are being used,etc...

This is something wrong with your iptables version or kernel <-> iptables version incompatibility. Does you host use nftables? IF not you need to load the nesseary kernel modes are switch the container to the iptables-legacy. In any case this is not a upstream buildah issue.
