Hi all.

I am currently troubleshooting a problem.

Before starting the tunnel when I check with mtr icmp and tcp/1194
availability of my external openvpn server's IP I get ~0% packet drop rate.
So overall network quality is good.

When I start the tunnel and check icmp and tcp/443 availability of a host
from a remote network from behind the openvpn server I get ~75% packet drop
rate :) So it looks like despite the fact that quality of connection
between the client and openvpn server (external, routable ip addresses) is
good inside the tunnel (private ip ranges, tun interfaces) the quality of
the link is ~terrible.

When I use the same config:

dev tun
persist-tun
persist-key
cipher AES-256-CBC
auth SHA1
tls-client
client
resolv-retry infinite
remote 1.2.3.4 1194 tcp
lport 0
tls-remote OpenvpnServerCa
pkcs12 xxx.p12
tls-auth xxx.key 1
ns-cert-type server
log /var/log/openvpn-client.log
verb 3

on a ubuntu 14.04 and 15.04 instead of mac OS X 10.10.5 it works very well.
Any clues?

BR,
Rafal.
