navaismo he probado con lo que me comentas y he abierto el puerto 8016 pero lo raro es que si lo hago cambia el puerto de forma automatica.
luego cambie y abri del puerto 8010 al puerto 8050 para tener un rango y evitar en udp
y cuando llame cambia y usa el 8052 luego abri del 8010 al 8060 por ampliar y cambio al 8062
