hi all: i have just read advance route howto and maillist,then i try to limit bandwidth. i installed a computer,the os is Redhat 7.0,there are two net cards.then i set two ip range,192.168.1.0 and 192.168.2.0,so i connect each othe in ipmasq,then i divided bandwidth in Commands of Adv Route howto,then i found i can limit upstream,i can''t limit downstream.i think tc can''t know ip address which has been masqed. then i read howto again,i found,i must setup a linux router if i want to limit upstream and downstream.then i look up some software,gated can do this? who can tell me how to setup a linux router? LRP? thanks lihao
