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

	ifconfig_wi0="inet ssid myap channel 11 mediaopt hostap"

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

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

	subnet netmask {
                option broadcast-address;
                option subnet-mask;
                option routers;

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