Istio ambient cannot do hostname-based egress filtering without L7 processing (waypoint/sidecar). Cilium FQDN CiliumNetworkPolicy is the right tool — DNS-aware L3/L4 enforcement. - Remove waypoint deployment and namespace/service label references - Move TheLounge HTTPRoute back to Cilium external gateway - Add CiliumNetworkPolicy for znc: allow DNS + irc.passthepopcorn.me:6697 - Remove orphaned znc/egress.yaml (Istio VirtualService routing) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
