Hello, I installed Release 8.0 from ISO and not upgraded to any newer version (I gave up with upgrading system to 8.0 stable or head version because of problems with recompiling kernel after upgrade). I recompiled kernel with additional options: ============================================ options IPFIREWALL options IPFIREWALL_DEFAULT_TO_ACCEPT options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=500 options IPFIREWALL_FORWARD options IPDIVERT options TCPDEBUG options IPFILTER options IPFILTER_LOG options IPSTEALTH options DUMMYNET options ALTQ options ALTQ_CBQ options ALTQ_RED options ALTQ_PRIQ ============================================ in order to use ipfilter + ipfw/dummynet on router with NAT enabled. i also recompiled ipfilter with LARGE_NAT option enabled. My rules for ipfw looks like: ============================================ add 00100 allow ip from any to any via lo0 add 00200 deny ip from any to 127.0.0.0/8 add 00300 deny ip from 127.0.0.0/8 to any pipe 80 config bw 512Kbit/s queue 40 add 40000 pipe 80 icmp from any to any in add 50000 allow ip from any to any via em0 pipe 100 config add 60000 pipe 100 ip from any to me in recv em1 add 60001 pipe 100 ip from me to any out xmit em1 pipe 2 config bw 35000Kbit/s queue 1024Kbytes queue 22 config pipe 2 weight 6 queue 256Kbytes mask dst-ip 0xffffffff add 65202 queue 22 udp from any to any out xmit em1 queue 23 config pipe 2 weight 7 queue 512Kbytes mask dst-ip 0xffffffff add 65203 queue 23 tcp from any 22,25,53,443,80,110,119,5060,3724 to any out xmit em1 queue 24 config pipe 2 weight 3 queue 256Kbytes mask dst-ip 0xffffffff add 65204 queue 24 ip from any to any out xmit em1 pipe 3 config bw 35000Kbit/s queue 1024Kbytes queue 32 config pipe 3 weight 6 queue 256Kbytes mask src-ip 0xffffffff add 65302 queue 32 udp from any to any in recv em1 queue 33 config pipe 3 weight 7 queue 512Kbytes mask src-ip 0xffffffff add 65303 queue 33 tcp from any to any 22,25,53,443,80,110,119,5060,3724 in recv em1 queue 34 config pipe 3 weight 3 queue 256Kbytes mask src-ip 0xffffffff add 65304 queue 34 ip from any to any in recv em1 add 65500 allow ip from any to any ============================================ Everything works fine until I plug in em1 interface (LAN) cable. When LAN traffic starts to flow I get dummynet messages: Mar 7 12:07:04 urke kernel: dummynet: OUCH! pipe should have been idle! Mar 7 12:07:05 urke kernel: dummynet: OUCH! pipe should have been idle! Mar 7 12:07:05 urke kernel: dummynet: OUCH! pipe should have been idle! Mar 7 12:07:07 urke kernel: dummynet: OUCH! pipe should have been idle! Mar 7 12:07:09 urke kernel: dummynet: OUCH! pipe should have been idle!

Mar 7 12:07:18 urke kernel: dummynet: OUCH! pipe should have been idle! I noticed that Oleg Bulyzhin made patch for ip_dummynet.c and i applied these changes to sys/netinet/ipfw/ip_dummynet.c. But problem still occurs. Next, I downloaded ip_dummynet.c from Freebsd cvs including even newer changes to this file - problem still exists. Does anyone know what causes the problem? -- Thanks, Mat.
