udp clients

[Dallas Clarke <dallas.clarke@xxxxxxxxxxxx>]

Hello All,

I am running a udp client behind an iptables firewall, I can open a 
socket, send from the socket, but I can only receive one packet back 
from the server - all other packets are blocked.

Is this the standard way netfilter works, have I configured something 
wrong (straight out of the box fedora core 5).

This is a real problem from me since I can't expect every user to drop 
their firewall so they can use our client software.

Thanks

Dallas.
