R6300 + Cisco C3750G = no access to internet

I'm replacing a failing FVS328( I know the 6300 is not anything like the 328), and trying to simplify my network and move my wireless closer to the cable modem. The cisco is configured with multiple vlans, with each vlan using the Cisco as the gateway, and the cisco using the 6300 as its gateway. From the wireless everything works as expected. from the cisco I can ping and traceroute out through the 6300, but from any device on a different vlan, I cannot access the internet. The traceroute stops at the 6300 IP.

Any help would be apreciated.
