options BRIDGE in kernel.
The bridge works fine now. Except that I need to
"down" than "up" em1 when it has been unplugged for a
great length of time.
Someone mentioned to change
net.inet.ip.check_interface to 0.
Apparently there was a change in
net.inet.ip.check_interface where, in 4.10, it is set
to net.inet.ip.check_interface=0 and in 5.3 BETA2(and
in 5.2.1) it is set net.inet.ip.check_interface=1.
The above difference caused me alot of confusion when
I was initially testing the bridge to see if traffic
was passing through(I was trying to ssh out from the
bridge machine to machines on the em1(no ip) side).
I have a 4.10 bridge that is working fine so this
change was new to me.
Thanks for your time.
