Softether VPN + Windows Server 2019 RDP

[sajer]

Dear Community,


i have a problem, since we switched to Windows Server 2019. We are working in an RDP environment, so everyone is working on the terminal server.
Since those, who work directly connected have no issues, it has to do something with softether + windows server 2019 rdp combo.

I built this with Windows Server 2016 and we had no issues, but since using (and nothing else changed) the 2019 server, RDP is laggy as hell.

Did anyone encounter this problem? If yes, please give me hints, i tried already a lot of things but couldn't find the problem.

(softehter + windows (terminal) server 2016 = good while softehter + windows (terminal) server 2019 = really bad).

Thank you in advance!

Some have said that setting the MTU on the SE VPN server's ethernet adapter to jumbo frame helps.

netsh interface ipv4 set subinterface “Ethernet” mtu=4088 store=persistent
