Hi
I wrote in a thread last week that we have a Windows 7 console application that communicates with an embedded processor card using UDP. I have watched the communication flow using Wireshark and it looks fine. I have set, what I believe
to be, appropriate inbound and outbound rules for Windows 7 firewall. On one PC the application runs fine, but on another PC inbound packets on one port are not reaching the application.
The weird thing is that on the failing PC, if I start a Wireshark capture on the interface, the inbound packets do reach my application. As soon as I stop the capture the inbound packets fail to reach the application.
Please can anyone suggest why Wireshark is having this effect?
Best regards
David
