Hello,
I configured openVPN server with three clients. The connections between the server and the clients work fine. My problem is, if I download a file from the server via the VPN tunnel the download speed is limited by 1.1MB. I tried to modify the mtu because there are some posts which I found via Google but the speed did not increase. I hope you can understand my problem and you have a solution for me.
Here is my server configuration:
server xxx.xxx.xxx.xxx 255.255.255.0
port xxxxxx
proto tcp
dev tun
ca /etc/openvpn/ca.crt
cert /etc/openvpn/certificate.crt
key /etc/openvpn/certificate.key
dh /etc/openvpn/dh4096.pem
tls-auth /etc/openvpn/ta.key 0
