   Does the device at 192.168.1.2 have statics pointing back in for those subnets?  Also usually ping is blocked on a FW .

Hi Devendrakumar,

Please check on your router that supposedly doing the Nat tranlsation for your inside subnets has static-route point to back to switch's interface address 192.168.1.1.

thanks
