Or perhaps the state tables don't overflow, but rate limits apply regardless of connection state. In fact that would be correct behaviour I think. Rate enforcement has little to do with whether the connection table is full or not... I would guess that the OP's iptables configuration unwisely fails to discriminate between incoming and outgoing traffic. The solution is to exempt traffic sent from the machine from the rate controls. -- Viktor.
