I have been using VMware workstation but have never quite used the Virtual network scenarios
My Workstation version is 9 and following is my scenario
I am testing and learning the TMG 2010 server
My setup consist of Win2008 R2 as a TMG , with 2 network adaptors
VMnet 8 - Internal - 192.168.31.0/24
VMnet 1 - External - NAT with Host
VMnet8 (host only) selected for DC (192.168.31.10) and Guest Windows 7 Machine (192.168.31.130) i.e , they both are in the same VLAN
Now the problem is
1. I am able to ping the public IPs(Internet) from TMG server also I am able to ping DC server (192.168.31.10)
2. The Workstation machine( 192.168.31.130 ) is able to Ping the DC server (192.168.10.31) but the DC server is not able to ping the Workstation
3. The Worstation machine is not able to ping the TMG server
3. The DC server is not able to ping the TMG server nor the Worstation Machine
4. The TMG server is able to ping the DC server , but not the Workstation machine
Now I have done quite a few changes in the network adaptors to check if anything works to set all ping right, but it of not avail and i feel i have screwed up somewhere in the configuration of the VMnet Adaptors and completely am stuck
Please guide me or provide me necessary steps so that get of this problem
