Hello Folks, I have a small openvpn server, serving about 10 various clients running OS-es such as:
-Windows7 32bit -Windows7 64bit -Debian 32bit -Debian 64bit -Android 4.x All the clients have the same configuration file (except the cert directives), I only have issues with the 64bit Windows7 and this seems to popup on the net on other places. Sometimes I experience terrible slow page loads, when I run wireshark on the wifi or lan interface I don't see problems but when I look into the VPN interface I see all kinds of dup, ack, out-of-order, retransmission packets. Some other posts recommended decreasing the MTU for the VPN tap interface in windows, this was a bit of help: http://i61.tinypic.com/jskltk.png This is only the 64bit windows clients traffic on the graph, it was trying to suffer a steam update down. I decreased the MTU from 1500 to 1400 at 17:00 which clearly shows up. I also read that Windows 7 autotunes the MTU, not sure if it's true. Now comes the strange part, after rebooting the machine openvpn refused to connect with error code 31 on the tap interface until I set the MTU back to 1500. Then I tried to adjust the mtu through the tun-mtu parameter from the config but if I put this in then it always just said connection failed. I tried 3 recent 64bit openvpn versions, currently I'm using the latest stable. Does anybody else having this issues? It is not firewall related because I getting about the same results from different lan and wifi networks.
