How do I control or limit Internet bandwidth usage of users/computer/IP address in network with the help of iptables rules?
I have one static IP address which provides Internet (that is, WAN). I assigned this to eth0 and the local network IP address as 192.168.0.1 (LAN) which is eth1. This machine is acting as my gateway and DHCP server. If it is possible, can I use the MAC address to identify the machine?
