DON'T just have them browse right out! Cache/Proxy chain a couple of times - this will massively reduce your traffic, esp. if you also run a caching name server before your T1. I'd also recommend some kinda content/virus checker in the chain and the last 'hop' before the 'net being an application-level firewall (this would also running a caching name server, only serving requests on i/f 127.0.0.1). This is fine for at least up to 5k clients (with two 'chains', going out of two 6 Meg lines, to two different ISP at two geographic locations - we can manually switch all traffic through either pipe) Dom - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Dom De Vitto Secure Technologies Ltd.

They think they have about 25,000 desktops (Windows 95/98, shudder). How can I help them predict the amount of traffic they'll see on their T1 connection? Is there anybody out there running a firewall for 25K desktops that is willing to share an order-of-magnitude guess?
