However, when the bandwidth is high, there seems to be some buffer-problems. Suddenly my application stops receiving packets from netlink and no packets get through. First I thought it might be that I have exceeded the allowed queue length, but that is not the case. The id of the last received packet is well below 1024. Does anyone know what might be wrong or have any tips? Also, is it possible to adjust netfilter's buffersize? -Kristian
