Following is what I did when I booted my FreeBSD notebook:

The wlan0 interface is already created for me by rc scripts executing at
bootup. I've disabled authentication in my wireless access point
(Netgear WGT624). 172.16.0.{1,2,3} are my other boxes available on wired
network. I've a pf setup on this notebook, which I disabled later, as
you can see above. My rl0 interface also connects to the same router, so
I've removed 172.16.0.0/27 address assigned to my rl0, so I can assign
other address of the same network to my other interface wlan0.
If there is some information which I missed, please tell me ?
TIA
Ashish Shukla
