Problem is solved!
Sometimes oneself must be told to re-think what you think you already have
though of ;-)

(I'm not using DHCP for the record)

The network settings for the broadcom controller wasn't the same in windows,
but the same as the intel p/w 2915 wireless controller in windows.
IP for broadcom in windows was 192.168.0.225 /25 and .228 for the wireless.

My conclusion is that the netgear RP614 played along fine in the LAN.
For example I had no problem accessing it's web-interface.
BUT when it comes to do NAT:ing it must have remembered the MAC of .228
(since I had used windows right before freebsd) and the NAT function of it
refuse to understand that it has to use another MAC for sending back
information.

After changing the broadcom controller's IP in freebsd to 192.168.0.225 /25
it works perfectly.


Thanks to you all for your replys. I have still some endeavors left before
freebsd is like a hand in the glove on my laptop, but hopefully I won't
run in to "unresolvable" problems =)
