[Solved] Connection through Gateway very slow

frato

Hello everybody,

i set up an OpenVpn 2.3.2 on a FreeBsd 10.0 64Bit Machine. I use Mac OS X 10.9.1 (Mavericks) with Tunnelblick 3.4beta20 (build 3727) as OpenVpn Client. I can Connect to the Server and the Gateway works. The Problem is that the connection over the Tunnel is very very slow.

Results of a Speedtest with connected Tunnel (http://speedof.me/):
Download-Speed: 20 kb/s
Upload-Speed: 1,59 Mb/s
Latency: 25 ms

Results of a Speedtest without connected Tunnel (http://speedof.me):
Download-Speed: 56.57 Mb/s
Upload-Speed: 1,88 Mb/s
Latency: 17 ms

Client.conf:

Result of MTU-Test:
NOTE: Empirical MTU test completed [Tried,Actual] local->remote=[1557,1557] remote->local=[1557,1557]

What i have done so far:

1. Disabled comp-lzo (server/client) -> No improvement
2. Changin mtu seetings (mtu-tun) -> No improvement

Eventually anybody have an idea how i can fix this problem. When you need more informations please ask.

Many thanks and greetings
