Turns out I only have one PCI slot in the computer that I am doing this
on.  Have to look for a new system.

However, I still have a problem that I can't seem to solve.  I have set
up wpa_supplicant, ipfilter, ipnat, etc. and everything mostly works.
From that system I can get out to any place on the net.  When I try to
make it the gateway it doesn't work.  Here's what I have so far.

rc.conf:
hostname=dilbert.druid.net
ifconfig_wm0="inet 192.168.215.105 netmask 0xffffff00"
dhcpd=YES dhcpd_flags="-cf /home/darcy/svn/Druid/etc/dhcpd.conf wm0"
wpa_supplicant=YES
wpa_supplicant_flags="-c/etc/wpa_supplicant.conf -B -iathn0"
dhclient=YES dhclient_flags="-4 athn0 -pf /var/run/dhclient.pid"
ipfilter=YES # uses /etc/ipf.conf
ipnat=YES # uses /etc/ipnat.conf

ifconfig.athn0:
up
dhcp

ipf.conf:
pass in from any to any
pass out from any to any

ipnat.conf:
map athn0 192.168.215.111/32 -> 0/32 proxy port ftp ftp/tcp
map athn0 192.168.215.111/32 -> 0/32 portmap tcp/udp 10000:20000
map athn0 192.168.215.111/32 -> 0/32

wpa_supplicant.conf:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1
network={
    ssid="Chalmetterv"
    key_mgmt=NONE
}

And net.inet.ip.forwarding = 1.

I can connect to the gateway server from another host but when I
traceroute it goes to the gateway and stops.  I can't tell if it is
failing to go through the wifi or if it is not coming back.

Anything jump out at anyone here?

Thanks.
