Hi,
we are planning to share an internet connection (bandwidth around 1 mb) among 60 - 70 PCs.
In the past i have used proxy software to share a connection with 4-5 PCs so can the same be done with 70 PCs
Sometime back we had this problem at my office; when more than 10 users tried to access files form an XP system (simultaneously), the system refused to accept anymore connections.
we later discovered that the OS doesn't support more than  10 concurrent connections. will the same happen here?
So whats the best way to go about this and which OS would be more suitable

Also could you suggest some nice proxy software with the ability to restrict bandwidth based on mac id or ip

thanks,
Rajesh

XP's ICS will limit you to 10 concurrent connections, as you have discovered, but using a seperate proxy program should not.

As for proxies, I'm not aware of any that are combined with a bandwidth limiter, but here they are:

Rajesh,

The limits imposed by bandwidth are quite distinct from the capacity limits imposed by Microsoft's servers.

How many users can share a 1Mb connection to the internet depends upon what the users are actually doing. I have run many many users (over 100) on a slower connection, but they were, needless to say, not each downloading 1MB of data per page per minute.

Bandwidth can go quite far if you have a reasonable workloads. A good understanding of your workload is crucial to understanding what will and what will not, work.

I hope that the above is helpful.

In your situation, M$ does NOT want you using ICS.  They want you using Internet Security & Acceleration (ISA) server.  And of course, you would have to pay for the additional $$$.

Another good, cheaper one, is ... Wingate.  http://www.wingate.com/product-wingate.php

hi,

I think more important than a proxy software will be a firewall.
You're better off getting a decent firewall which supports proxy as well.

you may even want to consider one that has VPN capabilities, after all, with 70 users,
you never know what they may want next week.

further, firewalls, can let you restrict a lot more and control access even better depending
on how much money you spend on one.

for that many users, I would not be cheap on a firewall,
unless you like unauthorized people altering your servers, printers, as well as the rest of the network thru the night.

A broadband router seems like a good idea here. You'll need a switch setup to handle all the clients on your LAN, too. The number of router models available, with or w/o firewalls etc, is vast.

Thanks guys, my main concern was whether the system will allow more than 10 concurrent connections.
