Good evening everyone.
I have a little Problem, that i cannot understand.
I've set up OpenVPN (confs below)
Everything except of some DSLight Issues and Bandwidth works pretty good.
Now i want to find out, what the bandwidth problem causes.
If i connect to the OpenVPN Server i have a Bandwidth near 12-13MB/s which is very good.
This with Linux (Fedora) and Windows 10 as well.
Some Clients have the problem, that their bandwidth is only 20% or below.
Example: A Friend has 150K Mbit/s without VPN and 20K Mbit/s with.
My Server is not overloaded. There are enought CPU and Bandwidth ressources left. (I see that in my Icinga / Nagios Graphs).
Now my question: Why is the bandwidth for some peoples so bad?
Is it a TUN/TAP Problem? An Interface Problem?
They all have the same confs, so it doesen't make any sense for me.
(Speed was tested with Torrents, Parallel Downloads from Uploaded and so on..)
