IPTABLES limit bandwidth?

Hi,

I am trying to limit the bandwidth of a particular port and hoped I
could use iptables for this. I am aware of the --limit parameter, but I
don't know how to set it up to say, limit the outgoing throughput to
say 512Kbits/sec. Is this possible with IPTALBES or am I going to have
to try something else?

Thanks,

Mike

You should look for QoS and the tc command. Take a look at
the LARTC howto at http://lartc.org.

iptables --limit option is used only to limit the number of times a
particular rule is applied in a given time. I dont see how that can be
used to limit the bandwidth. Use tc to limit and iptraf/stakrate/bwm etc
to monitor.

I can in particular recommend Wonder Shaper http://lartc.org/wondershaper/
