It's not clear to me what you want to accomplish. Is the goal to limit traffic from clients on your inside network to make available some fixed amount of bandwidth for inbound HTTP connections?

What you are looking for is QoS(Quality of Service) - TOS (Types of Service) connections.

You'd have to compile these IP Costs into the kernel, I don't think the default RedHat kernel has them enabled.


Networking options
IP: use TOS value as routing key Y

QoS and/or fair queueing
 QoS support
 Traffic policing (needed for in/egress)

What you are doing is making the Linux box into a smart switch.

To control the different costs, you would use Ipfilter and jump to TOS to set the different bits.
ToS Packet Mangling

Here is a site that explains a little:

I set FTP to max on my firewall at home, I sometimes get speeds of 350KB (It seems to max out around there) per second over cable. :)

I do notice it does kind of strangle other PCs I have on my small network.  But its only my wife and kids complaining why the net is slow... my response was, I'm not sure why, my wife caught on after a few times, and now yells "Are you downloading again!"  :P
