Hello,

I have a US Robotics Router that has packet filtering.
I want to block download accelerator applications like DAP and Mass Downloader so that employees don't use these applications. I'm thinking about blocking the ports needed for these applications. What are the ports?

Thanks

That's the rub, the ports are ports you need, namely port 80. The simplest solution is to take admin rights away, if they users don't need to install anything or make system changes, that will solve your issue, they can still download them, however they will likely not be able to install them. This also helps in other ways, they will not be able to get spyware or viri too!

M$ seems to have caught on to best practices about 15 years after everyone else, Linux, Mac, Unix, BSD etc...

P2P software is also capable of using port 80 or 443 etc... so they are hard to stop, but easy to detect, we Snort to detect our policy violators: http://snort.org/

probably, I'll make bandwidth management to control this issue. I will install "Mikrotik" OS that can do advanced bandwidth management.
In the future, we have a plan to have Domain Server to control the PCs.
Thanks for the links. A very good information.

Regards,

Mohammed
