I was wondering what problems you have with TMG on a VM ? we have 2 overhere so i might learn something here :)
Usage wise appart from the little chop outs it is much better than the last solution and some of the new features like the safe search enforcer are quite good especially considering the rather rudementry filtering upstream.
You say you have Hyper-V working with TMG installed on to an image?
We have just purchased TMG and awaiting for it to turn up (Frog VLE Installation) and I did try and get it working on an image but strangely enough it caused a Loop on our network...
I since then have not tried to get it working. How did you get it working?
Did you have to create the network bridge on the VM? (Sorry far too used to saying images).
That is where I struggled, EIS have told me it needs to be setup as a network bridge.
Ffffff, Just looked this up propperly and it looks like there is a fix for the console glitch:
Hyper-V Update to Improve Network Stability - Forefront TMG (ISA Server) Product Team Blog - Site Home - TechNet Blogs
The network connection of a running Hyper-V virtual machine is lost under heavy outgoing network traffic on a Windows Server 2008 R2-based computer
So thats one down, just need to see if it is SEP causing the minor drops now. Sorry to the OP for derailing the thread.
That may be implementation specific, I have it setup as a gateway firewall/Cache/router that isolates the internal network from the external internet and makes sure we don't waste any of our limited and expencive bandwidth on things we don't need to.
If it is set up as a bridge with no routing then this could be causing some of the issues, I do question the idea of bridged traffic for a WAN though as it effectivly means spewing all your internal broadcast and possibly multicast traffic over your WAN link saturating it unnessisarily.
The way I have it set up is (for simplicity) a couple of physical NICs in the Hyper-V host, Each of these is assigned to its own Network in hyper-v manager and then there are two virtual adapters on the VM, one connected to each network. Then the internet router is physicly connected to one of the ports (which only goes to ISA) and the other is connected to the internal network.

Sorry EIS are our service provider.
Our TMG box is for linking through our service provider (Frog VLE onsite server) to access it all externally in replace for our current website (currently hosted by EIS).
I was told it just needed to be setup as a network bridge, not so sure about creating that when you need two network adapters on a virtual box. When I created two, thats when it seems to cause me issues and the moment I got it working was the moment a loop back occured.
Sounds like both adapters are on the same network, they need to be on seporate networks if you are running it as a gateway. It needs to sit between your internal network and your ISP. You can install it with a single adapter and just have it filtering and proxying stuff but you loose most of its compelling security features.
