admin 57e07d9777 opengist: remove the client-written X-Forwarded-For chain on its router (R-753)
echo RealIP — leftmost XFF into its failed-auth log lines. 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).
