Hello, I am running ipqueue and snort-inline. However, I find that the moment that I add iptables -A FORWARD -j QUEUE nmap scans slow down by an order of magnitude. It is quite important for me to understand why this is happening. Any help is appreciated. Also, the firewall machine cpu and mem load is real low, so it certainly doesn't see to be running out of capacity (10 Mb network) Could a machine start dropping packets even though there is not significant CPU or Mem load and where will it report dropped packets? The kernel has the br-nf patches loaded and the firewall is in bridged mode.
