Hello, my apologizes for writing this under Android, but I couldn't find [i]OpenVPN Connect Windows[/i]. I'm just learning from the beginning and see, you mostly speak about OpenVPN server, but I have bought a TP-Link Archer C2300 v2.0, which has built-in OpenVPN function, to which I can connect to with [i]OpenVPN Connect[/i]. My upload is 10mb/s, download is 40mb/s (on both sides), but I can get only 50 - 300kbit out of the connection. All I need is at least 2mb/s for one bookeeping program. I'm trying to make it faster for a month and a half (TCP, UDP, dozens of ports (allows only 1024 - 65535), but without succsess. Do you think there is a problem somewhere, or is this all I can get? I contacted even TP-link support, they said the router's OpenVPN can make 10mb/s with no problem. The router is connected right to the satelite of the internet provider. Also, it is strange, that when I connect to OPENVPN on the home's lan, when I'm inside my house, the speed is the same (50 - 500kb/s). Do you think anybode could help me? Thank you. Regards M.

You misunderstand (or maybe we do?). Don't use OpenVPN Connect Windows but download the Windows installer from here: https://openvpn.net/community-downloads

[/quote] Do you think I should use other router for the satelite and then connect OpenVPN router to it? There would be much more forwarding. Im connecting to my public IP, which is then forwarded to my OpenVPN router.

You need to pay careful attention to your openvpn logs. There may be problems due to your network. Set --[i]verb 4[/i] server and client and then check your logs for problems.

I can't acces it. Also, there is a broadcaster nearby, to which the satelite is pointed, so I don't think there also telephone for upstream.

Could you give me a link to a guidline, how to build Ovpn on a win10pro?

You may need to contact your provider for assistance.

Sure but you will need to know how it is configured.

Satellite links are known to have problems with openvpn but they would manifest as errors in your logs. So keep an eye on your server log.

I don't build on Windows - I use this:

Try adding --mtu-test to your client config and then see your log.

Be sure to connect over the internet to your server ...

Also, please post the details of your openvpn server version.
