I just did this on FreeBSD 6.0, so maybe my experiences can help.
My setup:
ziggy
------- wireless ______________
inet | |==========| wifinet |
-----|fbsd | --------------
| 6.0 |----------| wirednet |
------- wired --------------
ziggy serves DHCP over the wired and wireless links, and gets dhcp
from inet. Obviously I have two nics and a wireless card, which
happens to use the Atheros chipset.
In my rc.conf, I set up my wireless card:
ifconfig_ath0="ssid airport01 media autoselect mode 11g mediaopt \
hostap wepmode on wepkey `cat /etc/wepkey` channel 1 up"
ifconfig_ath0_alias0="inet 192.168.1.1 netmask 255.255.255.0"
and I enable ziggy as a gateway (I assume you're doing this already
anyway):
gateway_enable="YES"
Then I bridge my wireless and wired connections. I use the new
if_bridge, which isn't available in 5.4. You could probably use
netgraph bridging or the deprecated kernel bridge interface. An
example of netgraph bridging is in
/usr/share/examples/netgraph/ether.bridge
Once the interfaces are bridged, you should be golden. I run dhcpd on
ath0 to server DHCP on my wired and wireless lans.
Of course, the important part is the bridge. You could assign the IP
to your wired and bridge the wireless to that just fine, if you
already have some of that set up.
