do you have two nics? the 2megas internet is eth0 right? so you are tc'ing packets going out of interface eth0.

paquets are comming from eth1 for example? 
in such case you coutlf -t mangle -I PREROUTING -i eth1 -j MARK --set-mark {1|2|4|}
??

so packets going from internal (eth1) going out (eth0) are previusly marked.
im pretty sure about this.
hope it helps, good luck.
