Hello all- WHat I am trying to accomplish with this dummynet config is give priority to udp traffic, namely dns and tcp ack's so that I can send mail to our clients announcement list, as fast and efficient as possible without congestion. So basically, I need this machine to ba able to make dns lookups with out a problem and I need the acks to get back to my machine so that the SMTP conversation can take place with out latency. I am not sure if I have taken all that I need into consideration, but for now I could use some constructive criticism in terms of making it better. Using FreeBSD 5.2.1, I have: /etc/sysctl.conf : net.inet.ip.fw.one_pass=0 /etc/rc.conf : firewall_enable="YES" firewall_script="/etc/rc.dummynet" firewall_type="open" firewall_logging="YES" /etc/rc.dummynet : ipfw -f flush ipfw pipe 1 config bw 300kbits/s ipfw queue 1 config pipe 1 weight 100 ipfw queue 2 config pipe 1 weight 1 mask all ipfw add 100 queue 1 udp from any to any out via fxp0 ipfw add 101 skipto 1000 udp from any to any out via fxp0 ipfw add 110 queue 1 tcp from any to any out via fxp0 tcpflags ack ipfw add 111 skipto 1000 tcp from any to any out via fxp0 tcpflags ack ipfw add queue 2 ip from any to any out via fxp0 ipfw add 1000 allow all from any to any Can I make this better or am I even on the right road?? Thanks in advance for your help. Regards, Bob
