We have been thinking about the same sort of stuff, although we don't have a problem yet. I was never a Boy Scout, but 'be prepared' seems a good matter :-) Whatever you do, you need to know what your trafic profile is before you attempt to control it. There's multiple freeware tools out there that will allow you to get a bit of a traffic profile. Things like tcpstat are pretty good. Of course, you can also use NFR to get that info if you have it installed using the TCP by connection stuff :-). If most of your stuff is http the first thing you might want to try is a caching proxy putting one of those in place will probably reduce the requirement to access the internet for data significantly. Next you might want to try putting in one of the URL filtering products. SmartFilter is supposed to be pretty good and it works with most every proxy you care to mention. Of course, that might be considered too draconian, it's depends on your organisation. Other things you might want to try are products like packeteer that will allow you to control bandwidth for various services/IP addresses etc. I't works well, we've tried it here. If you don't like to pay, check out the QoS stuff available in recent releases of Linux. It is quite powerful and flexible, but you don't have the luxury of a GUI. If none of that works, well, you aren't a magician. If the demand is all legitimate traffic, you just have to upgrade the BW. Alex.

We've tried restricting various thing like Napster, Gnutella and the like with varying degrees of success, but as more and more users come onto our LAN/WAN we've noticed our performance decreasing. Rather than manage this at our firewall (with many many rules), I'd like to know how you manage your traffic. What do you use? I apologize if this question seems off topic, but thought I would toss it out there and see what comes back...
