Can DHCP services work without being the gateway device?

Can DHCP services work without being the gateway device? In the example
I'm trying to implement without buying new equipment.

* Linksys WRK54G/192.168.0.1/Gateway/DHCP disabled

* Linksys WRT54G/192.168.0.2/Router/DHCP enabled

Will the WRT54G hand out IP's correctly to all my
(wired/wireless)machines on the LAN without it being the gateway device?

In general, with a wired LAN anyway, you can have a LAN with a DHCP server
anywhere on it. Any computer connects physically to the LAN, broadcasts a DHCP
request, and gets an IP address from a DHCP server.

As long as you use WRT54G #2 as a WAP (the wireless equivalent to a hub), I
would think that you could run DHCP from either WRT54G #1 or #2. As long as you
connect one of its (wired) LAN ports to one of the (wired) LAN ports of WRT54G
#1, it should work as a WAP, but not as a router.

That's correct. I will be (uplinking) the WRT54G to the WRK54G.

Kevin,

Well, it should work that way then. It just won't be a router, it'll be a WAP
(a hub plus a radio).

Right. That's what I wanted to confirm. I'll give this a try tonight.
Thanks for your insight.

Great. Please do let us know how it works (or not). DHCP and WiFi association
are an interesting subject.

I got it configured but not in the manner I discribed in the original
post. Chuck, you were right. I had to make the WRT54G into a WAP
(access point). I also discovered that the DHCP service doesn't work
correctly if is not hosted by the gateway device (WRK54G). I wasn't
getting the providers DNS settings and my PCs couldn't acquired the IP
from the DHCP device. So the WRT54G is a WAP and the WRK54G is the
gateway/DHCP server.

Kevin,

That's a useful detail. Thanks for sharing that with us.
