    Cerrar puertos

    Hi there,
    to make a long story short, I had to reinstall my system 4 times in the last year due to spyware, worms etc., even though I am using Zonealarm and Norton AV.
    Now with my new system, I want to make things differently, that is better. I want to block the ports and mininmize the threat of getting intruders on my pc.
    I have a Zyxel router, probably a 643 (there is no proper name on the back).
    I try to follow ADSL
    Acceder al Menú Inicio -> Ejecutar y escribís lo siguiente: telnet sin escribir las .
    But when I type in the text the Ejecutar window disappears.

    Also, in internet explorer does not open.

    I need help, desperately.

      The default behaviour of most ADSL routers, including ZyXEL routers, is to block all the external WAN ports that aren't expecting an incoming answer to a previous outgoing connection from inside.

      Therefore, the typical question is "how to open" needed ports, but not how to close them. ;-)

      The default IP address for LAN interface is not the same in every ZyXEL product. Sometimes is but you can also find or other numbers. I can only refer you to the User Manual for that very exact model of router.
