Who Me Too'd this topic

Hi guys,

We faced an issue where users' traffic related to office applications from a system, on which Terminal Server is installed, gets dropped by the firewall due to the unknown source user. We are using Terminal Server Agent as the means of user identifications. Web browsing and traffic related to other applications pass through the firewall with no issue and of course, the source user is known for those traffics. At first, the source ports being used by those office applications were out of range of allocated ports on the TS, so we extended the range to the maximum value to no avail. Does anyone have an idea?

Thank you in advance.
