I have a spare PC with Freebsd installed on it.  Can I configure
this machine to be a wireless access point ?

just curious.

Probably.  I'm not too familiar with how the ad-hoc connections work, 
but i am certain that for a single client it would work.  Just get a 
wireless NIC in it, play a little routing magic, maybe look at the dhcpd 
port (dhcp server)

The NIC on the AP has to be able to support Host AP mode to work
as an access point. Netgear MA 521 *with firmware 1.3* are on
example for this.

Install a prism 2 card and do something like (assuming fxp0
is your upstream iface and wi0 your card in AP mode).

rc.conf
ifconfig_wi0=inet 10.0.0.1/24 ssid myap channel 11 mediaopt hostap
gateway_enable=YES
natd_enable=YES
natd_interface=fxp0

Then install from ports isc-dhcpd with a config like:

ddns-update-style none;
always-broadcast on;

subnet 10.0.0.0 netmask 255.255.255.0 {
range  10.0.0.10 10.0.0.100;
option broadcast-address 10.0.0.255;
option subnet-mask 255.255.255.0;
option routers 10.0.0.1;
}

You rpopralby want do add a crrect
option domain-name-servers 10.0.0.1;
etc, etc.

The above is not secure in any way - so you may want to add WEP
for a start and then get more serious; add ipfw packet filtering
and nail things shut.

From 'man wi':

Cards based on the Intersil PRISM-II and PRISM-2.5 chips also have a
host-based access point mode which allows the card to act as an access
point (base station).  Access points are different than operating in IBSS
mode.  They operate in BSS mode.  They allow for easier roaming and
bridge all ethernet traffic such that machines connected via an access
point appear to be on the local ethernet segment.

For more information on configuring this device, see ifconfig(8).

Once you get the device properly configured and working as an access point, 
you'll need to configure the computer as a gateway and add NAT into you're 
firewall.  For home networking, the choice between dynamic and static ip 
addresses is probably a question of personal preference.

Also, since different cards support difference levels of encryption, consider 
your security options before you purchase hardware.  If you're going to use a 
VPN, the choice of hardware shouldn't matter as much.

Best of luck,

Andrew Gould

I do exactly this (well the Freebsd box is also a
firewall and samba,web,ldap,mail and a few other things server)
man wi will give a list of most of the cards that support HostAP
mode if i remember rightly.

Check out the handbook on your machine, in /usr/share/doc/ for the
chapter on advanced networking; specifically the page labelled
wireless.html.
