I am configuring TMG 2010 with one internal NIC for internal networks and one NIC for External NIC. But the network has multiple internal networks. The internal NIC is configured with IP 172.22.33.1. But I have 172.22.35.0/24, 172.22.37.0/24...... and other networks in the inside part of the network. I am trying to configure it with a firewall client. But the client machines which are in different subnet could not ping and the firewall client is not detecting the firewall server.
The log which I get from one client machine says "The packet is dropped because FF TMG determined that the source IP address is spoofed". This is for all protocols.
I configured a persistent route for the other internal networks and added them in the internal network list. I enabled WPAD and configured it on the DNS server. but I could not access the wpad.dat file from the internal client machines
Can anyone help me for this problem. I am stuck in this issue.
