ipv6 experiments
Ensure garden-linux is booted with -allowHostAccess=true (and a reasonable grace time like 500m).
=============================================================================================================
IPv4 experiment
Start a netcat server:
nc -l <host IP> 5000
Create a privileged container:
curl -H "Content-Type: application/json" -XPOST http://127.0.0.1:7777/containers -d '{"rootfs":"docker:///ubuntu","privileged":true}'
