HIPS Blocking Network traffic in Virtual Machine

Hi All,

Have got to a point with testing HIPS where I've just rolled out the Firewall in adaptive mode, all seems well so far.  Have one issue though, I have a virtual machine (vmware) and ever since I enabled the firewall on the host have noticed that the virtual machine is unable to map drives to our servers and also have lost internet connectivity.  Have noticed in the activity log on the host that it looks like traffic to the virtual machine is being blocked.  I decided to create a firewall rule on the host to allow 'any' traffic to the vmware.exe, but still unable to get any network functionality on the virtual machine.  Also the virtual machine seems to have become noticably sluggish since activating the firewall in adaptive mode.

Anyone have any ideas or had similar experiences.

Make sure your VMware Guest is running in NAT mode, not Bridge mode.

Also, this problem is solved in the upcoming HIPS 8.0 release, which is due to be released later this quarter.
