Hi all,
I have a strange issue in accessing internet behind TMG 2010 from random users. Sometimes internet works fine and sometimes not. I have checked the monitor section and I found this alert "Global denied packets rate limit: The number of denied TCP and non-TCP packets per second exceeded the system limit. As a result, Forefront TMG reduced the number of records of denied packets that are written in the log."
I did the following:
- Increase the number of TCP and non-TCP requests in Flood Mitigation Settings.
- Add the range of my subnet in the exception section to allow all users.
- Disable Mitigation flood attacks and worm propagation.
And the warning still exist and it is not directed to certain host.
Thanks in advance.
