The AirLink router was not able to do what I wanted so.. I purchased an Access 
Point that seems to work much better, at least once or twice. However, I seem to 
be having problems with the dhcpd.conf file (at least that what it looks like to 
me). After bringing up the dhcp3-server I do not get the information for the 
wireless sub-net if I do a route -n.

The current dhcpd.conf file contains:

# DHCP configuration for CDJ Systems Wireless subnet of a Belkin Access point

ddns-update-style interim;
ignore client-updates;

subnet netmask {
           option routers;
           option subnet-mask;
           option domain-name-servers,;
           option ip-forwarding off;

subnet netmask {
         option routers;
         option subnet-mask;
         option domain-name-servers,;
         option ip-forwarding off;
         default-lease-time 21600;
         max-lease-time 43200;
host bear_den {
         hardware ethernet 00:11:50:45:7A:42;

In the above subnet ...139.0 is on eth1 (wired) and subnet ...139.32 is on eth2 
(the wireless segment). The host bear_den is the Access point itself as 
requested by the Belkin folks ( it should have a static ip assigned). At one 
point I had this stuff working, at least it showed up right (I think) in a route 
-n display. I have a laptop that I can use to test with. I have been able to 
connect to the access point from it and get an ip assigned(at least once). 
However, I must have changed something because now I and not... Where should I 
look to determine what I have done or is going wrong?

I am at my wits end here and my wife wants me out of her laundry room (where my 
firewall/server stuff is located on a high shelf, and normally headless)!

/etc/network/interfaces contains:

auto lo
iface lo inet loopback

iface eth0 inet dhcp

auto eth0

iface eth1 inet static

auto eth1

iface eth2 inet dhcp

auto eth2

End of stuff...

Let me know if you need me to examine any other file...
