There was a problem hiding this comment.
Lets discuss at working group meeting, but also would want to retain the refactor making the agent responsible for all firewall logic setup. Don't like going back to it being inside the stemcell builder. In the agent we can haven proper test coverage so we don't end up in the same situation in the future.

Add a UseMonitIptablesFirewall option to LinuxOptions that tells the agent to skip nftables monit firewall setup entirely. The Ubuntu Jammy stemcell will set this to true in agent.json, falling back to its existing iptables-based monit access control (via cgroupv1 net_cls + restrict-monit-api-access). NATS firewall rules are unaffected and continue to apply on all stemcells.
