Hi
Im running openvpn server on gentoo linux with TAP interface and UDP.
Recently, however, connection to my vpn server is very slow (100 KB/s) on file transfer (scp). Also Streaming is not possible at all anymore.
I have tried a wide variety of settings with regard to fragment, mssfix, etc. but nothing seems to have fixed the problem
On client log (Mac os X, Tunnelblick) i get a lot:
Authenticate/Decrypt packet error: bad packet ID (may be a replay): [ #3121 ] -- see the man page entry for --no-replay and --replay-window for more info or silence this warning with --mute-replay-warnings
When i transfer a file from host (scp), Wireshark shows the following

I also set up openvpn on my Asus router (tap, udp) and the connection is as bad as with my own server..
