Hi Sandeep,
The network admins told me to set the gateway to the esxi host ip address. After doing that it allowed my to finally ping the esxi host address, but nothing past that. The default gateway for the esxi host is 184.130.164.33. Setting the guest vm gateway to the same value doesn't seem to help. I assume that's what you were implying... ie setting the vm guest default gateway to the same gateway that the esxi host uses?
