buenas lista, ay en un estado de desesperación no tengo más que esperar sus conocimientos (eso ya que lo he googleado todo). el problema es que no puedo configurar correctamente un conexión vpn de windows a debian lenny con pptpd, el comportamiento ha sido extraño ya que en momento si conecta y funciona a la perfección, pero en otros se cae y no hay caso.... creo haber identificado el problema buscando por todos los log
