<div dir="ltr">It's probably due to their over commit, and it means your UDP packets are in queue until expired.<br>Since Israeli ISPs has learned the trick, I tend to believe ICMP packets have high priority, so that no customer will be able to complain.

Hi,<br><br>The company I work at uses openvpn extensively. We settled on UDP-based protocol as it is more effective than TCP based.<br><br>Inter-Israeli VPN connection works perfectly all of the time, whereas international VPN has erratic behavior on at least one ISP. I suspect the ISP (XFone 018) dropping UDP packets occasionally during peak hours for following reasons:<br>
<ul><li>ICMP ping to the internet-facing IP number of the VPN router works properly all of the time</li><li>over-VPN ping to some server has about 50% packet loss during peak hour (tested at 23:00)</li><li>on different ISP at the same time there was no packet loss<br>
</li><li>over-VPN ping on the same ISP worked perfectly in the morning hours</li></ul>Have anyone else noticed the same behavior?<br>What is legal status of such network traffic policing?<br><br clear="all">--<br><font color="#888888">Arie<br>
