Yes, the wireless LAN is its own PCI card in my firewall.  The SMC2602W is a
PCI card with the PLX chip, some kind of PCMCIA bridge.  Plugged into it is
a standard SMC2632W PCMCIA card with the Prism2 chipset that many people say
works great in Linux.  If you use the linux-wlan-ng drivers this device
would be wlan0, but those drivers didn't work for me.  I ended up using the
orinoco_plx driver that is mostly compatible with this chipset, and part of
the Red Hat kernel distribution.  With the orinoco_plx driver, the interface
shows up as an /dev/ethX device just like another NIC.

I think I will use several security methods like MAC addresses and port scan
detection on that interface, and have a script disable the interface if any
mischief is detected.  Fine for my house network, but wouldn't work so well
with many users. =)
