household-switchable trustProxy reads the leftmost XFF into its logs. Once traefik trusts the tunnel's fixed address (controller v0.286.0), the leftmost entry is what a stranger writes; with the chain removed the app reads traefik's X-Real-Ip or its peer, as before — never forgeable. Measured on 9202: a router with this middleware receives no X-Forwarded-For (felhom.eu audits/visitors-2026-10-01/A/P1).
