seguridad que programa podria para internet estar configurar configuracion conexion conecte como bloquear bloqueando aplicaciones acceso c# windows firewall

c# - que - Agregue programáticamente una aplicación al Firewall de Windows



la configuracion de seguridad o del firewall podria estar bloqueando la conexion windows 10 (8)

Tengo una aplicación que está instalada y actualizada a través de ClickOnce. La aplicación descarga archivos a través de FTP y, por lo tanto, debe agregarse como una excepción al firewall de Windows. Debido a la forma en que funciona ClickOnce, la ruta al EXE cambia con cada actualización, por lo que la excepción también necesita cambiar. ¿Cuál sería la mejor manera de realizar los cambios en el firewall para que sea invisible para el usuario final?

(La aplicación está escrita en C #)

Encontré este artículo, que tiene una clase de contenedor completa incluida para manipular el firewall de Windows. Agregar una aplicación a la lista de excepciones en el Firewall de Windows

El arenero ClickOnce no presentó ningún problema.

La forma más fácil que conozco sería usar netsh , simplemente puede eliminar la regla y volver a crearla, o configurar una regla de puerto, si la suya es fija.
netsh hay una página que describe las opciones para su contexto de firewall.

La respuesta es que solo permite que el software de confianza se ejecute con privilegios de administrador. De vez en cuando, ALGUNOS software deben tener privilegios de administrador y realizar cambios sensibles en su sistema. También podría tener un disco duro de solo lectura de lo contrario ...

No estoy seguro si esta es la mejor manera, pero ejecutar netsh debería funcionar:

netsh firewall agregar allowedprogram C: / MyApp / MyApp.exe MyApp ENABLE

Sin embargo, creo que esto requiere permisos de administrador, por razones obvias :)

Editar: simplemente no sé lo suficiente sobre ClickOnce para saber si puede o no ejecutar programas externos a través de él.

Suponiendo que estamos utilizando un Instalador de Visual Studio-> Proyecto de instalación: necesita una clase de instalador como esta dentro de un ensamblaje que se está instalando, y luego asegúrese de agregar una acción personalizada para la "Salida primaria" en la fase de instalación.
