RE: [leaf-user] OT - How many users will a T1 line service?
At a former work place (was an e-commerce web development company) had ~500 end users comfortably sharing a T1 (less spam :). Where I currently work, I'd estimate that ~300-400 comfortably share a T1 line. The work is not web related, email traffic through the line is appr 10,000 a day (5,000 spam). I'd have to ask the network guys how much traffic there actually is to. Set up MRTG to monitor bandwidth utilized from day one. MRTG is a free bandwidth montioring tool that helps with utilization trends (runs on Linux and Windows with perl). Couple things to incorporate. Underestimate usage if posible. Set email attachment limits NOW (5 megs is reasonable) if you don't already have them. Also, if you don't have them, set attachment type blocks as well. This will avoid email viruses. I put the blocks on down to a server level, that way, if a client gets infected, he bombs himself and I don't get stupid questions (I can email an exe to Bob at work but not to home, etc). If it's executable, then block it, they can zip it up otherwise and if they don't know how, they can learn. Consider also a web caching server, many queries will be to the same sites as people find the latest 'neat' site and send others to it. I realize you didn't ask about email, etc, but realize, once the pipe is out there, people will use it in unexpected ways. If they are not going to be getting pop mail through it, then make sure you block it at the firewall from day one! In fact, if it's JUST for web, open up 80, 443 and only what you need, otherwise, getting it locked down once it opens, will be almost imposible.

Re: [leaf-user] OT - How many users will a T1 line service?
From experience on the far end of the line, a T-1 can hold anywhere from 2 to 1000 users simultaneously. If this setup is mostly web browsing for research purposes - for example, a school library - where they either won't want to or won't be able to run their own programs on it, then a frac T-1 should do okay. If you've got more than 50 users though, I wouldn't go much below 512k. Also, consider Frame Relay. It's often cheaper, and can be set up so that you have, say, 768k most of the time, with a burst capability up to full T-1 levels. It also allows you to go with a good many more ISPs. Note that this is conditional on the number of simultaneous users - or more to the point, the number of available workstations. And below a certain speed rate, people are going to grumble about slow speeds no matter how many folks are using it. Also, I've seen full T-1s range in price from as little as $300 per month to as much as (or more than) $1000 per month, exclusive of any equipment charges - T-1 routers are expensive! Make SURE that, if it looks like you're getting a good deal, the price of the service INCLUDES the price of the local loop; That $250 T-1 deal might be pretty crappy if your site is 5 miles out from the CO and you've got to pay for the charges yourself. Steven had a point as well; if you're doing e-mail, limit attachments - I prefer 10 megs, to allow larger PDFs and MS Bloatware application files through - right off the bat. Set up a transparent caching webserver, probably (to tie it in) in a LEAF DMZ, with the bulk of users on an inside network to get a solid firewall going. If you're doing your own e-mail, set it up so that the e-mail server is also on the DMZ, and make sure that you've got it set up to scan for virii. This will also allow you to set up something like SpamAssassin. After that, I strongly recommend IMAP rather than POP; even on a local network, you'll get a much easier time of the bandwidth usage. If someone else is hosting for you, request IMAP specifically, then block POP. Someone downloading a fistful of SoBig e-mails is one surefire way to clog up even a T-1 line.

In fact, if it's JUST for web, open up 80, 443 and only what you need, otherwise, getting it locked down once it opens, will be almost impossible. I take it you mean impossible from a political point of view, not technical...right? Once they've tasted the fruit of unlimited access, they will be much less willing to give it up.
