Здравствуйте, freebsd-questions. You need to add queue's and forward all you inside subnets to those queues smthing like this ${fwcmd} pipe 1 config bw 128Kbit/s queue 20Kbytes ${fwcmd} queue 1 config pipe 1 weight 50 queue 20 mask dst-ip 0xffffffff ${fwcmd} queue 2 config pipe 1 weight 50 queue 20 mask src-ip 0xfffffff ${fwcmd} add 40000 queue 1 ip from any to 192.168.1.128/25 via em0 ${fwcmd} add 40001 queue 2 ip from 192.168.1.128/25 to any via em0 > Hi ! > > I have FreeBSD 4.8 installed. > There is IPFIREWALL, IPFIREWALL_FORWARD, IPDIVERT and DUMMYNET in my > kernel configration. > On my FBSD gateway to the Internet I would like to use NAT (of course > :-))) ), transparent proxy and limit the outgoing traffic. > xl0 (62.169.170.166/30) is the public interface, xl1 (192.168.1.1/24) is > the private one. > > If my firewall rules look like: > ipfw pipe 1 config bw 256Kbit/s queue 40Kbytes > ipfw add 47 pipe 1 ip from any to any out via xl0 > ipfw add 48 allow ip from 192.168.1.1 to any > ipfw add 49 fwd 192.168.1.1,3128 tcp from 192.168.1.0/24 to any 80 > ipfw add 50 divert 8668 ip from any to any via xl0 > ...
