te explicare detallado
para conectarme a internet configuro cualquiera  de los navegadores con el ip del serviod y proxy 3128
y luego empiezo a navegar pero ya a partir de la 6:00 pm no puedo revisdar nigun correo email por la web en internet, incluso cuando trato de conectarme a este sitio e identificarme me sale un error de denegacion que no puedo revisar web email, igual,pasa cuando trato de descargar algun programa y me pide direccion de correo y contraseña... me han dicho que esto es por causa del firewall que ademas controla mi horarior de descargar, o sea que solo puedo descargar a partir de las 12:00 de la noche hasta las 6:00am, entonces que me dicen por cierto
si puueden envienme el http tunnel por correo que me hace falta para probarlo ya que muchos me dicen que funciana pero si crees o tienes algo mejor que esto espero me puedas ayudar.. gracias navego con internet explorer,6.0 mozilla firefox,ect
Que debo hacer para quitarme tantas restricciones

No tienes que abrir varios hilos para lo mismo continua la discucion en uno solo.
 :angry:

no creo que sea un spyware, mas bien cuando termina turno simplemente bloquean los puertos, porque no lo se quiza para evitar el espionaje corporativo, como salir hay varias formas una es la que dices httptunnel otra es cambiar el puerto mediante el cual navegas.
Citar
La solución que yo he encontrado es tener un servidor externo cuya misión es recibir peticiones web por el puerto 443 y reenviarlas a la dirección adecuada por el puerto 80. De ésta manera, desde el trabajo, realizo la petición de conexión segura por el puerto 443 a la dirección donde se encuentra el programa "pasarela". El proxy intenta realizar la conexíon segura con dicha IP, el programa pasarela lee entonces la cabecera HTTP y hace la petición al servidor adecuado por el puerto 80, que responde de vuelta a la pasarela, ésta confirma al proxy la conexión segura y reenvia los datos recogidos al proxy que, al estar bajo conexión segura, no filtra nada y entrega todo a mi PC en el puesto de trabajo.

El código fuente del programa pasarela lo coloco aquí:
