To work around this, I used `update-alternatives` to change iptables and
ip6tables from iptables-nft to iptables-legacy. At least things function
now. (I'm using docker.io and putting RKE's Kubernetes on top of it).
It appears that workaround allows the networking to properly work, and
also implies that Docker is manipulating the tables using some other
method than /usr/sbin/iptables (confirmed in the moby ticket below).
I tried starting dockerd with iptables=false, but Kubernetes really
needs thorough networking to function.
