Hello! We have a problem... Dlink 3426 is core of our network. DGS 3612 - routers, which are connected to core (users). Core is connected to bridge. There are three interfaces igb0, igb1, igb2 on bridge: igb0 - local network igb1 - border1 igb2 - border2 Bridge is are shaper (ipfw). border1 and border2 are connected to bridge. Border1: FreeBSD 7.0-STABLE-200807 i386 Border2: FreeBSD 7.2-STABLE-200906 i386 Bridge: FreeBSD 7.2-STABLE-200906 amd64 Traffic is devided between two borders. We have not got any problems with border2. But on border1 we have: ping through border1 from users and from bridge ping ya.ru PING ya.ru (93.158.134.8): 56 data bytes 64 bytes from 93.158.134.8: icmp_seq=0 ttl=58 time=95.083 ms 64 bytes from 93.158.134.8: icmp_seq=1 ttl=58 time=102.876 ms 64 bytes from 93.158.134.8: icmp_seq=2 ttl=58 time=113.630 ms 64 bytes from 93.158.134.8: icmp_seq=3 ttl=58 time=90.352 ms 64 bytes from 93.158.134.8: icmp_seq=4 ttl=58 time=127.349 ms 64 bytes from 93.158.134.8: icmp_seq=5 ttl=58 time=115.942 ms 64 bytes from 93.158.134.8: icmp_seq=6 ttl=58 time=103.753 ms 64 bytes from 93.158.134.8: icmp_seq=7 ttl=58 time=124.507 ms But in border1 we have: ping ya.ru PING ya.ru (213.180.204.8): 56 data bytes 64 bytes from 213.180.204.8: icmp_seq=0 ttl=61 time=3.130 ms 64 bytes from 213.180.204.8: icmp_seq=1 ttl=61 time=2.909 ms 64 bytes from 213.180.204.8: icmp_seq=2 ttl=61 time=3.791 ms 64 bytes from 213.180.204.8: icmp_seq=3 ttl=61 time=2.953 ms 64 bytes from 213.180.204.8: icmp_seq=4 ttl=61 time=3.298 ms 64 bytes from 213.180.204.8: icmp_seq=5 ttl=61 time=3.096 ms bridge: 1). netstat -w1d -I igb0 input (igb0) output packets errs bytes packets errs bytes colls 32442 0 19375201 29681 0 23220291 0 31894 0 19334182 29124 0 23043942 0 31566 0 18885017 28558 0 22390016 0 31810 0 19200993 28768 0 22270687 0 31879 0 19347245 29145 0 22795440 0 31697 0 18997706 29274 0 22651927 0 32042 0 18963695 29634 0 23508103 0 30674 0 18123997 28432 0 22890282 0 31654 0 18519433 28860 0 22918799 0 31961 0 19145696 29418 0 23238031 0 32056 0 19053994 29723 0 23775215 0 32367 0 18952231 29771 0 23774054 0 2). netstat -w1d -I igb1 input (igb1) output packets errs bytes packets errs bytes colls 21378 0 19903174 21410 0 9866489 0 21444 0 19948761 21752 0 10266869 0 21435 0 19972984 21825 0 10289265 0 21318 0 19748715 21431 0 10238696 0 21606 0 19855988 21467 0 10483023 0 21825 0 19956737 21750 0 10452641 0 21665 0 19805016 21980 0 10711357 0 20937 0 18983521 21357 0 10506764 0 21241 0 19280484 21992 0 10713008 0 21469 0 19652542 21667 0 10391424 0 21235 0 19538130 21524 0 10757572 0 20779 0 18963762 21003 0 10525245 0 20853 0 18854491 21312 0 10559890 0 Those commands on border1: 1). internal netstat -w1d -I em1 input (em1) output packets errs bytes packets errs bytes colls 9862 0 8286463 8226 0 4172860 0 10060 0 8603460 7209 0 3184874 0 9290 0 7781648 7709 0 3672720 0 9720 0 8311391 7208 0 3545028 0 10256 0 8669129 8232 0 4678531 0 9509 0 8140150 7715 0 3878637 0 9554 0 8081766 7199 0 3512477 0 9426 0 8046217 7721 0 3867273 0 9795 0 8177803 7721 0 3729722 0 9637 0 8297993 7199 0 3766607 0 9671 0 8275210 7202 0 3510855 0 9451 0 8306122 7196 0 3535604 0 9324 0 8009044 7202 0 3092661 0 9715 0 8265237 7364 0 3575433 0 9908 0 8215978 7499 0 3911766 0 9776 0 8270432 8086 0 4178572 0 2). external netstat -w1d -I em0 input (em0) output packets errs bytes packets errs bytes colls 8253 0 4640677 9803 0 8495567 0 7897 0 4878726 10041 0 7322200 0 8368 0 4776220 9832 0 8565609 0 7650 0 4285985 9283 0 7717595 0 7891 0 4352473 9797 0 8134889 0 8606 0 5018218 9657 0 8289548 0 8460 0 4720658 10207 0 8397786 0 7543 0 4085187 9277 0 8059337 0 9376 0 6040976 11500 0 8860064 0 8181 0 4552212 10295 0 8582838 0 8774 0 5079266 10062 0 8494193 0 8193 0 4674008 10295 0 8520010 0 10170 0 7212068 10813 0 8596957 0 8499 0 4936674 10828 0 9090783 0 8416 0 4409607 10297 0 9050824 0 7613 0 3960242 9280 0 8231506 0 A few month ago border1 in this configuration worked succsessfully..
