Welcome to the Community - You really have 3 choices for configuring networking in VMware Workstation -
- Bridged - when a VM has bridged networking it will appear on the physical network
- NAT - This where workstation acts as a NAT Firewall - generating IP addresses for the VMs so they can communicate to each and beable to access resources from your production netwrork but are hidden from the production network
- Host Only - The VMs are on a network that is completely blockeed from your production network
Reviewing the Workstation will help you further - http://www.vmware.com/support/pubs/ws_pubs.html
I have also moved this to the Workstation Forum -
