Discussion #916 Message: 2009-10-26 06.28.15 strick

This is "WinDump.exe udp" output, on Windows XP.

These are fragmented UDP packets, typically 10K to 30K size. They leave the XP box successfully & arrive at 75-144-20-99 successfully. When 75-144-20-99 sends a packet back, it looks like only the first fragment (with the UDP header) makes it back.

Why not the other fragments?

The same kind of fragmented UDP do arrive back -- through the exact same routers & masquarade -- on a linux box on the same network, same switch, as this Windows box. So I think the problem has to be in XP.
