Necesito insertar en iptables para abrir 8080.
Con los iptables que miré iptables -Les tan complicado y tiene muchas divisiones que no estoy seguro de dónde poner la regla para abrir el puerto.
Aquí está mi iptables -Lsalida:

No soy un experto en iptables, pero mirando tu configuración la respuesta es:en ningún lugar.
La segunda línea, tanto en las cadenas INPUT como FORWARD, parece permitir todo desde cualquier lugar a cualquier lugar, por lo que agregar explícitamente una regla para un protocolo y número de puerto específicos no tiene mucho sentido.
