I'm not sure if this correct forum (already published in TMG forums), I published the topic here, too.
We are trying to deploy site to site VPN with Azure according the site below
TMG is configured in 3 LEG permiter mode. When initiating TCP port 500 connection to Azure gateway IP address, the following error is generated (A packet was dropped because Forefront TMG determined that the source IP address is spoofed).
TMG version: 2010 Service Pack 2 Rollup 2
