Does anyone have any ideas? http://tldp.org/HOWTO/Adv-Routing-HOWTO/ Bandwidth limiting outgoing traffic is called "shaping" and can be done very flexibly: "Queueing Disciplines for Bandwidth Management" http://tldp.org/HOWTO/Adv-Routing-HOWTO/lartc.qdisc.html /usr/share/doc/iproute-2.4.7/README.iproute2+tc Bandwidth limiting incoming traffic that's not being forwarded is called "policing" and can be done only by dropping excess incoming packets. That's not too bad for tcp as tcp will recognize that condition and slow its transmission rate. "Chapter 14.
