  • Hi

    How can we find out which application is using which port like google talk, web interface applications like Trend Micro Antispyware EE etc. so that ports can be configured.

    Hi,

     

    all new IM and P2P apps do not use special ports.

     

    They started to use HTTP & HTTPS protocols.

     

    To Block them, you have to know their signature.

     

    HTH,
