Yes the network is set perfectly as is.Did you follow the part about setting up networking in the handbook?
I have a number of 2950 (II and III) FreeBSD servers with the same network chips which are working fine.Hi, I have a Dell 2950 III server which has 2 inbuilt network cards, both are Broadcom NetXtreme II .
# ifconfig -a and the contents of /etc/rc.conf? /var/run/dmesg.boot would also be useful.
