dsl router does DHCP and so does Linksys routers

[pbxphoneman]

I'm seeing lots of customers hooking up linksys wireless/wired routers to DSL routers that are doing DHCP also.I believe the Linksys stuff comes defaulted out of the box doing DHCP? Isn't this a conflict having my DSL routers doing DHCP and the customers LINKSYS routers doing the same? OR....when my router is plugged into the input side of the linksys it gives an IP to it from its pool (dsl router) and then the Linksys gives out IP's from it's pool to all other stuff hooked up to the LAN side or ports on it???
Maybe it's ok because they are on two different subnets?
I know it's a no-no to have 2 DHCP servers on the same subnet.
any explaination would be kewl...thanks!!!

You should disable DHCP on the wireless router, and configure it just as an access point - I have just set that up right here:

The DSL router hands out the addresses, if possible reserve some of these addresses so that you can assign a static one to the wireless device (otherwise you get the problem that I currently have - not knowing the address of the Wireless router!!) - your wireless clients make a connection to the network via the wireless access point (think of it as a wireless hub)and are given an IP address by the DSL router on the same network.

See this for a good discussion of the issue, and how to deal with it:

Here are your options

1) you could run to 2 DHCP servers but the downside of it, if you don't configure your network right your can't share your files and printer on your network. If a pc is connected to the first DHCP it will not communicate with the pc's on the router cause you must consider the firewall of the router, but the pc's behind the linksys router could communicate to the first DHCP pc's.

2) or you could just disable the DHCP of the router and put the linksys router to router mode (that's on the advance and then dynamic routing) for easy pc networking
