Dear community users,
I've successfully setup a continental wide openVPN network from UK to Russia. The openVPN server ist hosted
in the Netherlands with a 200/200Mbps connection (glas-fibre)
All clients have normal land lines 100/100Mbps minimum connection. (Upstream and downstream is always 100Mbps minimum)
Except 1 client who's located in Germany. The connections in Germany are still somewhere in the 70ties of the last
century and thus upstream is 1Mbps at it's best, or if you are located in "lucky" areas you get a 10Mbps upstream in
Germany.
For this reason, I've made a connection by satellite with this client. Sat offers 20Mbps down and 6Mbps upstream, which is
6 times faster then what the telecom companies in Germany can offer in over 85% of Germany.
This actually works great, up and downstream are as advertised and doesn't slow down during specific hours, which is usually
the case with normal German telecom companies.
However, over VPN the connection is somehow limited to 128Kpbs inside the openVPN network. And this is real weird. If
i copy 1 file insinde the openVPN network, the speed is 128Kbps, but if I open a 2nd copy process, this one also gets 128Kbps,
if I do a 3rd, this one also gets 128Kbps, etc.. By using 10 copy processes at once, I achieve around 1Mbps..
On 50 Connections I still get 3Mbps (Assuming the heads of the remote HDD are getting hot here)
So, how can I get the combined speed of all those simultaneous copy processes bundled within 1 single copy process? If the openVPN
tunnel can achieve those speeds, and the DD-wrt routers support it.. then there must be a setting to allow the 3Mbps with 1 single copy
process.
Anyone have an idea how to configure openVPN properly for satellite links?

Re: openVPN over Satellite
So here's another issue..
when using FTP over the openVPN Network I manage to get 600Kbps per connection.. with 8 connections I total up to over 4 Mbps..
When using windows/osx/linux/smb file copy default mechanisms I only get 128Kbps per connection..
Any reason why using FTP over openVPN would be 5 times faster then default file copy?
I assume windows/osx/linux all use samba since the server they are copying from and to is a windows 2012 server..

Re: openVPN over Satellite
I have exactly the same problem (The one on the first post). Was going to open a new thread but found this one that explains exactly my problem.
I have a dedicated server when I have an OpenVPN server and a computer behind a satellite with the same conditions as the user explains (Maybe same company). When I switch the satellite router to a 3G router it goes as expected, with the same client and such.
Some iperf3 tests (reversed, to test download, and 20 seconds, to let satellite catch-up)
Satellite test directly, without VPN:

3G test without VPN:

As you can see, in the 3G one only a small overhead is noticed, but on satellite the bandwidth drop is really big.
BUMP!
