how much load can be managed by proxy


Here the Internet connection is through 128kbps modem. 40 PCs are connected through server to the Internet. I have 2 questions.
1. Can i use proxy and ipchains simultaneously? (half through ipchains, half through proxy)
2. If i connect the 40 PCs through proxy, how will be the performance?

A proxy be very efficient depending on the brower traffic of your users. If your users have common areas of surfing, you should get very good results. I have connected 25 users to a proxy on a 56K modem line and gotten acceptable response. Everybody liked it alot better when DSL came to town though.

Generally, I block port 80 at the router for all except the proxy box.

Well proxies handle application traffic at the protocol level, ipchains handles traffic at the network and transport layer, so they handle two different areas of the network stack and they can be used simultaneously on the same traffic. You can even use ipchains to force all outgoing HTTP request to go through the proxy (so no settings changes are required in the user's browser!).

Oh, running Squid (I assume that's the proxy you're considering) will require a good deal of RAM and a fast hard drive. If you run it on the same box as your firewall, you should make sure it's a fairly fast box (at least P3, probably best to have 1GH CPU, 512-1024MB RAM, 20GB+ 7200RPM+ HDD).

Thanks for the information.
I am really glad to tell this matter to our network admin.
