Hi,

I am quite new to networking and its concepts. Would like to know how to block the YM and MSN Messenger and control downloading from websites at an user-ip level, so that i can enable the messenger and downloads per request.

Request you to give me steps in a descriptive manner , as I am really very new to this field.

Thanks for your support.

Regards
Nisha

If using 7.2 then you have some options using advanded http inspect rules:

# Yahoo Messenger uses the following ports:
# 5000 (TCP - Chat)
# 5001 (TCP - Chat)
# 5055 (UDP - Phone)
# 5100 (TCP - Webcam
MSN messenger works through port 1863

Block these ports in your firewall rules
