Don't reach a network , even when I add a route to the TMG machine

Hello,

Hello,

I attach the image so it is easier to understand.

Basically, as the drawing says, I am trying to reach DC1 from TMG2, but I am unable. To achieve it I just added a route (red-coloured in the image) to the TMG2 machine, but the log keeps telling me "Packet dropped because the ip is unreachable."

I really don't know why it is that the machine can't get to DC1, the firewall is off.

Also, TMG1 allows all the icmp traffic from the Perimeter to the LAN.

I have a question: TMG2 sees 192.168.2.0/24 as external, I don't have a definition for such network in the TMG2 machine. There is the NAT relation between the Perimeter network and the External , and I am wondering if this is what is causing all the issue.

I edit the post to ask another question:

I have a route relationship between the LAN and the Perimeter network in TMG1, I wonder if that should be a NAT relationship between those two networks.

Thanks in advance!
