Re: blocking broadcast.com ip addresses
We use Little Brother software. It runs on an NT server and can monitor and/or filter traffic based on specific sites, categories of sites or by netbios name on the workstation so if you don't want billybob listening to music but the president cant live without it, you can get the job done. We implemented it about three months ago and got back nearly half our Internet bandwidth. -d ""Kathy Miihalisko"" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Very well put!

Re: blocking broadcast.com ip addresses
We did have an employee that went to some site that streams sound just using their web browser. I'm not sure which site this was but we were running proxy based firewall and I was surprised to see her using it. To cut the story short, we put out a memo that said they're not supposed have these and that their access are being logged. On the technology side, you might want to use some kind of layer 4-7 switch which would be much easier for you in terms of blocking out certain sites as opposed to blocking ip addresses. beth shriver <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Can someone tell me how to block traffic from/to > broadcast.com ???

RE: blocking broadcast.com ip addresses
Very well put! Remember how, a few years ago, the Push technology had us all screaming about bandwidth robbery. In our case the first albeit not only step was to update the company network policy to prohibit its use. But with increased services and snoops on the Internet, things are even more complicated now. Just doing a simple -netstat on a PC reveals all kinds of mysterious activity. This morning I found an electronic bill-paying service which I've never heard of opening a TCP connection to my machine. Freaked me out. Chuck's right, there are good 3-party tools if your org. can afford them. If not or in the interim, a freebie scanner will help you monitor and associate port activity on your IP hosts, and your findings should be reflected in enforceable policy as well as your configs. (By the way, registered ports 2938--2942 and 2861 appear to be used by broadcast.com for radio/voice but there's also a mass of basic port 80 activity and beaucoup remote hosts when you start their service.

RE: blocking broadcast.com ip addresses
Hi, first, issue a nslookup (on Xnix) or a ping -a (on Winxx) to find the ip addresses, then use an ACL to block traffic to thoses IP @. My favorite is an ACL on the inside interface, as I don't want to route packets I will discard just after. Should be something like : int E0 (Your inside interface) ip access-group 101 in ... access-list 101 deny any host log # deny broadcast.com access-list 101 permit any any # accept everything else Remember : in the first line, you may have to use a range of IP @ for broadcast.com, or you may have to put some more line, one per IP @ The last line is mandatory, as an ACL has an implicit deny any any at the end. Hope this helps, Jean-Marc On 05-Jan-01 beth shriver wrote: > Can someone tell me how to block traffic from/to > broadcast.com ???
