I have an application I wrote that received UDP packets from remote sites. I have a new router, and some new internet security software. I disabled the security software and could not find any router settings (NetGear) that would affect my computer getting these UDP packets. I forwarded the port (12007) as I have done with other routers and other applications that use the port forwarding work. I have a local application I can run to test that sends packets via the internet and back to my computer. How can I tell that is happening to these packets and why they are not being received? Thanks for any ideas. Knowing how to diagnose and identify the fault would probably help me when my customers cannot connect to the internet or client-server database. -Johnnie Back to top Marc Wetzel Guest Posted: Wed May 16, 2007 8:12 am    Post subject: Re: How can I trace blocked UDP packets? Have a look at wireshark (www.wireshark.org). This tool is a packet sniffer (before known as ethereal). It installs a kernelmode packet driver, so you can see all incoming and outgoing traffic. Another nice tool (based on the same source IIRC) is packetyzer. Search google for this, as I dont know it very much.
