Hi everyone! I have the same problem. I can identify whit wireshark that the problem was traffic RDP(UDP). But this isn´t the big problem, because if the connection did´t pass through a Checkpoint Firewall it works, but when pass through the FW CKP the traffic UDP RDP is the problem.
The solution in windows: you must change this in the client that open the connection RDP and dont use UDP protocol:
- Press Win+R to open the Run box. Run gpedit. msc.
- Navigate to Computer Configuration > Administrative templates > Windows components > Remote Desktop Services > Remote Desktop Connection client.
- Enable the Turn off UDP on client setting.
I want find why this happens in FW checkpoint? someone knows?
Sorry about my poor english.
