Thread: Bandwidth Limit with Iptables

Dear Sir

I have 1024/512 bandwidth

so I want to litmit bandwidth with port.
want to use 512/256 with port 80
want to use 256/128 with port 443
want to use 256/128 with other ports

can I setup with iptables ?
Pls instruction to me

thanks

For this task

Put ur webserver behind squid proxy and create delay pools for them

and from Iptables use this so nobody will try to cheat and use a proxy server other than ours. Public proxies usually run on 3128 and 8080 port

must also make sure that nobody will try to cheat and connect to the internet directly

Put all this in /etc/rc.d/rc.local

You can use various things to control bandwidth. Iptables itself can be used to throttle bandwidth. Checkout the following:
