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

A few month ago border1 in this configuration worked succsessfully..
On border1 there is yandex driver for em.

dev.em.0.rx_kthreads=4

I have made the same options in sysctl on border1 like on border2:
kern.ipc.nmbclusters=262144
net.inet.icmp.icmplim=200
I have added a new option
net.inet.tcp.sendbuf_max=16777216
net.inet.tcp.recvbuf_max=16777216
net.bpf.bufsize=4194304
net.bpf.maxbufsize=8388608
But have no ane good results.
