Hello,
          I have Backtrack 5R2, Windows XP & Metasploitable-2  inside the VMWARE Workstation, i need Backtrack machine to communicate with other two vm's & download updates,surf internet, so what will be the network setup in this case ? please suggest me..


Regards.

Bridging should work, but beware that this now means your virtual environment is now connected to your LAN. Any attacks, malware, etc that you unleash could hit your production systems and beyond.

This can get particular interesting if you're experimenting with layer2 attacks for the first time, not that I have first hand experience of course...... *whistles*

It's a little dated and doesn't still match my current setup (I need to spend more time in the lab), but I covered my VMWare network set-up some time ago. Hopefully it will help give you some ideas/pointers.
