Hi all, Since i have recently updated my main Windows 10 workstation, I've got some RDP dropped connections. The connection drops for 2 seconds and reconnect. A quick wireshark analysis revealed that the RDP protocol is requesting UDP port 3389 traffic to the target RDP server. As per Sophos UTM, the RDP protocol definition is TCP:3389 (which is also what I've had in mind). Did anyone saw such behaviors ? I'm pretty reluctant to add TCP & UDP port 3389 for my RDP rules. Although i'll test this now to acknowledge if that is counter measuring my issues... Thanks, Regards, M.
