Cisco 1921 – Sub Interface Access to Internet

cisconat;routingsubnetvlan

I have set up a sub interface on Gi0/1 and I would like to provide access to the internet for devices on the VLAN that routes to Gi0/1.200. The devices pick up DHCP addressing just fine but cannot access the internet and do not see to route to 0.0.0.0/0

Can anyone please help me with what I am missing? Here is my running config
