Stop online radio feed?

[gerryR]

Hi guys

I know this may be in the wrong area but hopefully someone has an answer.

We have an office of about 80 users using mainly w2k and wXP. We have a dsl
line connecting to the internet and to our other offices through vpn.
Although several mails have been sent around people are still using media
player (and real one) to listen to online radio. Unfortunatly the users
require these programs for some legitimate use although listening to online
radio is never needed. Does anyone know of a way to stop this? There is a
noticable draw on our line because of this.

We don't use a proxy server of any kind and would like to avoid this if
possible.

I appreciate any help on the topic, or any advice anyone may have.

cheers
gerry

use your network monitoring tools to find someone who is doing it and fire
them. that should get the attention of anyone else thinking of doing it.

Little bit drastic, was hoping for an inbetween solution to take away their
ability altogether.

cheers anyhow

Get a good firewall appliance and allow outbound ports 80 and 443 only (and
110 for POP if needed, etc etc etc).

That should stop at least *most* of this. You need a firewall anyway,
really - NAT in your DSL modem isn't enough.

Cheerrs for the reply, we have a hardware firewall in place already. Is
there a particular port that just online radio streaming uses ?

Nope - it uses a gazillion of them. That's why it's a lot easier to close
all but the ones the users actually need.

Not drastic, at all. After all, these employees _are_ stealing
from their employer, aren't they?
