Descriptions

Envoy before 1.16.1 logs an incorrect downstream address because it considers only the directly connected peer, not the information in the proxy protocol header. This affects situations with tcp-proxy as the network filter (not HTTP filters).

Envoy versiones anteriores a 1.16.1, registra una dirección posterior incorrecta porque considera solo al peer conectado directamente, no la información en el encabezado proxy protocol. Esto afecta situaciones con tcp-proxy como filtro de red (no filtros HTTP)
