Unstable RDP - tweaks?

I have installed FG on a debian12 with 3 cores and 6Gb of RAM.

I noticed RDP to servers behind FG are regularly freezing (every few minutes) but it’s not all the servers at the same time (= server 1 RDP is freezing but server2 RDP continue to work, then it will be server3 that freezes during 15 seconds and so on).

On one of the RDP servers, I launched a permanent ping to the FG server : no loss
Also have a permanent ping from my computer to the FG server (through the internet) : no loss

  • permanent ping from FG server to one of the windows server: no loss

When the freeze occurs, no error is logged on the FG client.
The target platform hosting the servers have a 100Mb internet connection (which is barely used).

A ‘top’ on the debian shows the machine is very idle.

From a platform perspective, FG and Windows servers are on the same network with nothing between them.

In //, I have setup direct RDP to these servers over the internet and without using FG, it is smooth and never freezes.

I also tried hosting the FG public IP on the VM itself instead of the fw without a better result.

I’m not sure if FG is able to handle RDP, if a tweak has to be done in its configuration thus asking if someone has a working setup with FG to perform RDP.

Thanks for your feedback :slight_smile:
