Hello, I examine the version 3.0.0 as a solution for implementing virtualization in the company where I work in.

I wanted to work with NAT on“Vista 32 Snapshot”, but what is happening is that I am losing packets when pinging to the external servers in my local network from this Virtual Machine.
Same is not happening from the host machine ( I tested on Linux Fedora 11(x64) and on Windows Vista x64 as host machines) so I can determine that the problem came from the Virtual Box.
When you switch the network mode to bridge mode all is working fine with 0% network packet loss, when I revert snapshot to the original state with NAT (without snapshot) all is working fine with 0% packet loss.
Same is happened in the previous version 2.2.4.

Can you please let me know what is the problem with NAT and Snapshots and what should I do in order to fix this ?

There is a known problem with NAT on VirtualBox 3.0.0. Please try to downgrade to VirtualBox 2.2.4 or wait for the next maintenance release which fixes the problem. See here.

Hi Thank you for your answer,

Same happened in 2.2.4
