Network outside internal not reaching TMG Forefront 2010 (Hyper-V environment)
- by Pascal
Below is my environment:
I have 1 physical machine running Windows 2008 R2, with the Hyper-V role. This machine has 3 physical NICs:
One for Internet
One for Internal Network
One for Wireless Network
All 3 have their respective Virtual Networks in Hyper-V, and I have an extra Private virutal machine network for a DMZ Network.
In one of the virtual machines, I have TMG Forefront 2010 SP1 installed, with all 4 networks available to it. Below is the IPCONFIG /ALL at the firewall:

I have the Networks below at Forefront:
External: IP addresses external to the Forefront TMG Networks
Internal: 10.50.75.0 - 10.50.75.255
Local Host:
Perimiter: 192.168.10.0 - 192.168.10.255
Wireless: 192.168.1.0 - 192.168.1.255
In the Networks Rules, I have:
1 => Route => Local Host => All Networks
2 => Route => Quarantined; VPN => Internal
3 => NAT => Internal; VPN => Perimiter
4 => NAT => Internal; Perimiter; Quarantined; VPN; Wireless => External
My problem is that I can only communicate with the Internal and External networks. If a ping www.google.com or 10.50.75.21 from the Forefront VM, I get answer backs without a problem. If I try to ping a machine at the Perimiter network or the Wireless network, it doesn't get routed back to Forefront, and it's the default gateway on all Networks. Here as ping samples:

The ping to the 192.168.10.3 gets the Destination host unreachable. Below is the ipconfig for the perimiter VM:

Trying to ping 192.168.10.1 ( the gateway ) from the DMZ machine also does not work.
When I use Log & Reports to monitor packets from Wireless network and Perimiter network, I don't get any packets link PING or HTTP that I try to send. But I do get a lot of spoofing messages for NETBIOS broadcasts... it's like Forefront thinks it's coming from a different network, but I don't know why. Please Help!
