Did you try to enable ip forwarding in /etc/sysctl.conf? Perhaps this
is, why packets aren't send "from one to the other side".

Yes , and no. I've both tried with
net.inet.ip.forwarding=1
and
#net.inet.ip.forwarding=1

In both cases same trouble.
If not manually /sbin/ifconfig up
or giving them a IP in /etc/hostname.epX
no bridging.

did you check the status with ifconfig -a? perhaps it's - like in most
cases - just an error in a filename e.g. bigdename.bridge0 or something
like this. What does ifconfig bridge0 return?

Jupp,

From my first posting,

---
cat /etc/bridgename.bridge0
add ep1
add ep2
up
---

As my first posting states, if I only have
up media 100baseTX
in the /etc/hostname.epX files, it doesnt bridge, if I
put some rfc1918 address (eg 10.0.0.2 10.0.0.3) it
bridges...

And,
/sbin/ifconfig ep1 up ; /sbin/ifconfig ep2 up
bridging works.

/etc/sysctl.conf
#net.inet.ip.forwarding=1
as I dont want this to be a layer-3 , but a layer-2.

>What does ifconfig bridge0 return?

bridge0: flags=41<UP,RUNNING> mtu 1500


Fyi, I have pf=NO in /etc/rc.conf , as I want to make
the box actually _bridge_ by itself before I put any
rules.
