Yes, it is. All my LAN is cabled with cat. 5 not crossed wirecable.

Trying to ping 192.168.254.1 on ttyv1
I've got this output, using "tcpdump -vvv -i dc0" on ttyv0:

tcpdump: listening on dc0, link-type EN10MB (Ethernet), capture size 96 bytes
May 7 14:26:30 guildurno kernel: dc0: promiscuous mode enabled
14:26:54.394958 arp who-has 192.168.254.1 tell guildurno.engineers
14:26:55.203946 arp who-has 192.168.254.1 tell guildurno.engineers
14:26:55.321328 arp who-has 192.168.254.1 tell guildurno.engineers

3 packets captured
3 packets received by filter
0 packets dropped by kernel

"guildurno" is my host name and "engineers" is the domain network name.

> Can you ping yourself? (127.0.0.1 and 192.168.254.3)

Yes, I can ping myself, both address' 127.0.0.1 and 192.168.254.3

> other than that... im pretty stumped... dodgy NIC?

If you mean something like "broken" with the term "dodgy",
I cannot understand why my NIC works with others OS.
But I'm not sure that is the right meaning for this word!
..I've got some english troubles too! ^_^

I think it's turned off on my bsd machine.
I've looked on my rc.conf file, and I've found out:

firewall_enable="NO"

I've tried to boot my system using FreeSBIE 1.1 (dvd bootable).
Perhaps cause a bad system installation,
my network interface didn't work (..no harm in trying).
But I've still found out the same network problem.
I can't ping any machines connected to my LAN.

Yes, I've got a switch (Edimax Fast Ethernet 8 ports)
When I started to figth this network problem, first of all I tried to
lock the speed (like you wrote to me) but with no results. :-((

Thanks again guy's
