This post was last edited by user_3002329 at 2018-2-1 17:26. Hello. I doing a simple project in the eNSP and have a problem. I'm using a "server" (router) and PC (I tried to use two PCs). They are connected with a switch with default configuration. I send an udp  packet from the PC to the router and analyze the trafic in the Wireshark.

I have this:

1) I send one UDP packet (udp dst port=122); Wireshark display only one UDP packet on the PC interface ; Wireshark display only one UDP packet on the router interface.

2) I send one UDP packet (udp dst port=123); Wireshark display only one UDP packet on the PC interface; Wireshark display TWO completely identical UDP packets on the router interface.



Why is the udp (NTP) packet duplicated?How to disable this?

eNSP ver. 1.2.00.510

WireShark v 2.4.4

WinPCAP 4.1.3 (4.1.0.2980)
