Hi

I Installed Forefront Threat Management Gateway 2010
2 LAN
First Connected to External Internet router at 10.0.0.1
Second to Lacal Network at 192.168.0.0 - 192.168.0.255
Local Gateway address (The Machine I installed on) 192.168.0.150
Gateway (forefront TMG)  is in Workgroup Mode

My questions:

1. I understand that only one DNS must be set in the Gateway (forefront TMG) in the external LAN in My case  the First Connection 10.0.0.1, is that correct ?

2. What should I set for each computer inside my Local Lan for:
    The Default Gateway ?
    The DNS ?
    Should I need to set Proxy server in each computer to 192.168.0.150 Port 8080 ?

1. No - dns mus ONLY be set on the INTERNAL nic and must point to the INTERNAL dns server. Nothing should ever know about the external DNS except the DNS forwarders in the YOUR DNS server service.
2. default gateway on internal PC's/Servers will be the TMG internal IP adrress.
3. As above, the Internal DNS
4. Yes

5. These are absolute basics not only for TMG but for Windows generally. I would suggest you read one of the good admin books or get yourself on a course else TMG will trip you up significantly. It is not forgiving when you get it wrong - if you do not know the detail of how it operates then to make it work people often have tp put in entries that also open big holes in their security without realising it.
