c# - Cannot pick up packets with UdpClient.Receive, but wireshark sees them -


i'm doing embedded development, , i'm sending udp packets board simple listener written in c# however, c# client never receives anything, despite packets being detected wireshark.

when board sending messages , listener not running, see alternating udp packets , icmp error packets in wireshark. when start listener, error packets disappear, nothing received.

i have tried sending computer instead, , works fine. , comparing packets pc board reveals no apparent differences.

screencap of packet board in wireshark: http://i.imgur.com/wmz37n8.png

i'm lost here, appreciated.
