Welcome to the Community,
you are posting in the vSphere Hypervisor forum, but as I understand your question you are talking about a hosted product like VMware Workstation, Player or Server!? Wether your virtual and physical systems can ping each other depends on your network configuration and - also very important - on whether the Operating System's firewall allows pings. E.g. Windows 7 and Server 2008 R2 block incoming pings by default.
