The haproxy edge holds its own DMZ VIP, a second public entry point alongside traefik-external that must be firewalled and DNS'd separately. Traefik can front it with TLS passthrough, leaving haproxy's certs and backends untouched. - Add a `traefik-external` Gateway: HTTP :80 plus Passthrough TLS :443. - TLSRoute the 12 `fe_https.map` hostnames to haproxy:443; HTTPRoute 301s :80. - Make the Service ClusterIP on 443 only, releasing 198.18.199.1. - Drop `fe_http`, `be_letsencrypt` and `fe_http.map`; certs are DNS-01 only. Client IP now reads as a Traefik pod — the Gateway provider cannot emit PROXY protocol to a TLSRoute backend. `sessionAffinity` goes too (it would pin Traefik pods, not clients); SRVNAME cookies keep persistence.
