Sorry - I didn't think this through in your setup - normally on
a setup with two ethernets, you would also have rules to block
'normally routable' traffic, destined for your internal networks.

If your cableco/ISP could _force_ 192.168.x.x destined packets at
your 'firewall', it would route them with your current rules. Since
there's no way to add the rule you really need, you need another 
ethernet card, as I said before.
