Ubuntu to windows transfer speed issue

faxi

Hey guys I'm pretty new so forgive whatever mistakes I unknowingly make.
I have a server with ubuntu 14.04 on it. I setup openvpn on it so my friends could access the shared drives. I did not have it assign gateway. I just wanted them to see the drives not route all traffic though it.
I've managed to get them into the network and map the drives. But the problem is the transfer rate is slow than I expected and fluctuates like crazy (anywhere from 300kbs to 650kbs)
Also when the client sends something back to the server if it's generally over 20 MB the connection is interrupted.

I've been reading a bunch and have tried some tweaks such as mssfix and mtu changes also the sndbuf and rcvbuf at 0 and a bunch of other numbers. I've also tried changing the protocal to tcp and disabling fragmenting or something to that effect.

I feel like I'm aimlessly putting things in the config and getting no results. I do mirror the changes client side.

port 11194
proto udp
sndbuf 250000
rcvbuf 250000
;dev tap
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh2048.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
duplicate-cn
keepalive 10 120
comp-lzo
user nobody
group nogroup
persist-key
persist-tun
status openvpn-status.log
verb 3
tun-mtu 1500
fragment 1415
mssfix 1410

I manually went through the config file and removed the comments since the grep command didn't work.
If you guys have any suggestions it would be much appreciated.
Thank you.

which is probably caused by the intervening networks not OpenVPN.

This may be due to TLS renegotiation, See --reneg-sec in The Manual v23x

faxi wrotetried changing the protocal to tcp

UDP VPN is faster than TCP.

Not a good idea ..

I presume you are using Samba for shared drives, try a different file transfer protocol .. FTP is ok over a VPN as the packets are encrypted by the VPN.
