Please can anybody provide a tc script and any other necessary detail to manage my bandwidth that can just fit into my network. These are what I want to achieve.
 
1. I want to dedicate 32K for my IP phone to have a clear phone call.
2. I want all the computers on my network to share the remaining bandwidth(N.B My ISP allocated a    bandwidth of 64K uplink and 128K downlink) in such a way that all    the computers must share    equal bandwidth and none of the computers should exhaust more than necessary bandwidth to    disturb others.Also the bandwidth should be shared based on the number of computers that are    active. i.e if few computers are available at any time they can use all the bandwidth shared    evenly.
 
My intended network configuration are stated below:
 
1.I have a Linux box runing RH 9.0 with two network cards one(eth0) connected to my      ISP gateway modem with default gateway IP as 10.0.0.254.The other network card(eth1) connected directly to my 24port hub   through which my entire network is connected.
2. I assigned a private ip address to eth0 192.168.1.1 and 192.168.2.1 for eth1 .
3. I have up to 20 workstations which I will assign ip address ranging from 192.168.2.3-22 with    their gateway set as 192.168.1.1.
4. I have also set up the same Linux box as a proxy server to allow all http request from all computer on my LAN except 3computers with ip address 192.168.2.20-22
5. My ip phone with ip address 192.168.2.25 cannot be under the proxy server also. 
 
I look forward to your assistance. Thanks.

Can be done.

??  Eth0 is connected to your ip so you need an ip address on eth0 that's in 
the network of your ISP and this propably done with dhcp.

Shouldn't the gateway be 192.168.2.1 ?

This can be a problem.  If you want to shape traffic and you use a proxy 
server on the same box, you don't know if the object was fetched from the 
cache or from the internet.  Try to create a dedicated proxy server.
