Avinash, what happens if you just unplug the cable modem? It may sound like the same thing, but it would be interestig to know if the cable modem is broadcasting alot of traffic through the firewall.
In order to help confirm this, you will probably have to supply the mailing list with the firewall rule set you are using as well as the config information of both of your ethernet interfaces, your routing table `route -n` and possibly your resolv.conf file as well.
