I have created a superscope on our DHCP server and added a secondary IP range of 10.10.5.0.1 - 10.10.5.254.
I have also added that IP range to the internal network on the Forefront TMG server.

All the IP addresses on my orginal range work fine, but any addresses from my new range get blocked by the TMG server and give this error:-

Status: A packet was dropped because Forefront TMG determined that the source IP address is spoofed.

anyone know how i get round this?
