Double Router Setup
I have got a problem. I have setup Small Business Server for my Uncle/Aunt at their business that they run out of their home. I have set things up with a linksys wireless router which is connected to their broadband connection. This provides access to the internet to the computers in the house, which are not part of the SBS network. The small business server has two nics, one of which is connected to this router and therefore uses a 192.xxx.xxx.xxx ip for the wide area network. The second nic is connected to the second linksys router which just acts as a switch... My problem is that SBS requires that I don't have any other DHCP servers on the network, either internal or external, but when I do that and set the DHCP scopes on the SBS to have one for the outside network, as the are on different sub-nets, the outside computers can not pickup an ip address. I have set these computers to use a static ip for now, but I would like them to be able to pickup ip addresses from the server, as they have clients that will connect to the outside network from time to time to access internet and print....

Sorry for the delay, I got it working for the time being and got busy with some other things. I want to have two subnets with the computers that are in the house to be separte from the computers in the office.
Wireless Network(Home)

Wired Network(Clients) Office Networks
This is kind of how it is set up right now. I have disabled the wireless on the second linksys router as well as all NAT functions and DHCP(running as just a switch). The first router also has DHCP disabled, but is still providing NAT functions as well as the routing that this requires. This is because of a lack of public IP adresses. The home and client networks are not supposed to be part of the office network, to provide a higher level of security for the office network. It is true that the office computers eventually use the first linksys router to get to the Internet, but I would like all DHCP to happen from the SBS as this is how it (SBS) was designed to run. I have two scopes setup in the SBS DHCP, one using the subnet of the "Wide Area Connection" and the other using the Local Area Connection. This should, I think, assign IP address depending on the network the request is comming from.
Again sorry for the delay in responding...

Thanx
That is how I already have it set up. As I searched more about this topic I found some information that has led me to believe that the router just won't pass the DHCP through the wireless. It works fine with computers that connected to the swith on the outside linksys router, but not through the wireless. I'll give the points for the help anyway.

1) Disable DHCP on SBS.
2) Remove wired router from network and use a switch or disable all routing function on wired router.
3) Enable DHCP on wireless router.
4) Configure NAT on the router if necessary.
Since everyone is going out to the internet using the same switch, they will be in the same subnet and DHCP will be handled by the router.
Wireless Router => Switch => SBS
Is this what you are trying to achieve?
