hi,
our TMG has two network cards: for External network - 193.219.57.20, internal - 10.0.30.49.
I can't access internal web server (10.0.30.50) through TMG server. I get errorr SPOOFING_PACKET_DROPPED (Status:A packet was dropped because Forefront TMG determined that the source IP address is spoofed).
As I read "The only reasons packets are denied as spoof are that either the ISA Server does not have the source IP in its address range for that network or if ISA does not have a route to it."
Our route table is:
