Connectivity Issue

[spaceage21]

I have a cable modem connected in router g0/0 receiving dhcp and g0/1 internal lan connect to switch. I am able to ping the outside world from router but not switch and can't figure out what's wrong. Please Help

Hi spaceage21,

Without knowing your configuration, my guess would be a NATing issue. 

See if this helps:
