Hi Ovo,
It looks like UDP packets got dropped somewhere.
1.Routers/firewall
If some traffic control get enabled, some packets, including UDP would be delayed or shaped, Since ping (icmp) is a simple protocol, it may lost packets when UDP packets lost.
2.socket buffer
OS may drop packets from socket buffer when busy. You can adjust the socket buffer size of NR client. Please take a look at the performance tuning guide of NR,
http://download.neorouter.com/Documents ... 111_en.pdfNR clients may create UDP P2P connection between peers. Unlike TCP, UDP is an unreliable protocol, so it's possible to lost packets. However, the applications over NR network should be able to handle it.
Thanks,
