Punkbuster kick: no packet flow.

Hello,

I played today on the server with King_fisher (friend of phoenix), but gets kicked by punkbuster every 2 minutes. It says, no packet flow. Does anyone know what it exactly means and how to solve it? I thought it was something with you packets that can't go trough firewall or something but I don't know. Hopefully someone knows how to handle so King_fisher can play again
