Re: Let APs do DHCP ?

said by Airplane777 See Profile :

At my hotel hotspots, I let my router hand out the IP addresses to all WiFi users. But...

I'm thinking of turning off DHCP in my router and turning on DHCP in each of the APs.

When I remote into my Internet gateway routers, I will see the IP addresses of the users. But with the router handing out IP addresses, I won't have any idea at all which AP a users is on (or at least the AP he originated on, assuming he didn't walk around the hotel and hand off to another AP).

I have one hotel with 11 APs and I would like to know which AP a particular IP (user) is on. So I figure if I let the APs do DHCP, and knowing the IP range assigned to each AP, I will naturally know the AP each user originated on.

Am I correct in my thinking there?

Thanks.
Might be correct, some may disagree, but my general feeling is the less the AP has to do as far as network backend the better.

I may be wrong here...but here's my thought...

If each AP were a different segment (for example, 10.1.0.1, 10.2.0.1, 10.3.0.1, etc), and you had a DHCP on the backend of your AP's configured with seperate scopes, I would think that the server would hand out IP's based on which AP the client connects to.

On my home network (Windows 2000) running DHCP, I have my wireless router on a different segment from the rest of my network. The DHCP server in W2k hands out 10.23.0.x addresses for the wired network, and 10.23.1.x for neighbors connecting to the wireless.

Bob, On a small network/AP that only has a few users per AP, You would be fine running DHCP in the AP. When it gets loaded up is when the trouble starts. Most AP's need all the horsepower they can get above 30 users, and DHCP is just another thing to add strain to it. Most of the AP's that I have worked with have an arp table in them showing all of the MAC's that are local and ones that it sees but are remote. If You look in the router to see which MAC is associated with which IP, You could then look at the arp table and see what MAC is coming thru which AP. It might be a little more of a hassle?, but at least the router is still taking care of DHCP.
