Hi Everyone,
We are having a bridge and throughput issue with a live network bridge on
an Openbsd 4.6 firewall here.
root@luigi:/var/tmp# uname -a
OpenBSD luigi 4.6 GENERIC.MP#89 i386
There are no errors on any other interface. Some interfaces are autoneg and
some are full 100 statically set. (Normally I associate network errors with
negotiation mismatch however I'm baffled how this can happen with a bridge)

I have upped the states incase that was an issue
root@luigi:/var/tmp# pfctl -sm

src-nodes hard limit 10000
frags hard limit 5000
tables hard limit 1000
table-entries hard limit 200000
root@luigi:/var/tmp# ifconfig bridge0
bridge0: flags=41<UP,RUNNING> mtu 1500

Would anyone have any ideas what I can try to see what is causing this
issue? I have already tried disabling pf with pfctl -d however it doesnt
make a difference. Also goggling around shows up practically nothing
resembling. Any help would be very much appreciated!
Many thanks!
Stephen
