Hi everyone,
we use the TMG 2010 server as a firewall with two NICs in routing mode. I have observed that the TMG changes the sequence number of outgoing TCP packets. This is problematic for our application. ATM I think the TMG relies on this "feature" for its IPS. Are there other reasons why the TMG would change the sequence number?
Is there a way to turn this off?
What I have tried so far is turning off all IPS/IDS features and disabiling Kernel Mode Forwarding, which had no influence on the sequence numbers.
Thank you,
Moritz
