Hi Paul, We use TMG in our environment, once it's all setup it works fine. I think the main benefit is as you mentioned it will authenticated against your DC before letting any traffic in as per your rules. We've had issues in environments with over 2000 users (memory issues) where the firewall policies wouldn't go into effect and we'd need to restart the services. I guess the answer is it really depends on what you're trying to do. What's your primary reason for considering another solution? Is your current firewall not meeting some requirements?

I wondered what peoples thoughts are on using TMG to proxy Exchange 2010 OWA/RPC/ActiveSync access? We already use a firewall that does SSL inspection and only allows access to the Exchange virtual directory URL's so I'm not entirely sure what benefits using TMG (solely for Exchange) would give us? If I understand correctly, the primary one seems to be that as you're authenticating to the TMG gateway, and if you don't authenticate you simply cannot throw exploit attempts at the IIS that's sitting on the Exchange boxes?
