 I  was wondering if someone might be able to help me understand how to configure two wireless routers so that one is a work LAN with internet access and the other is a guest LAN with internet access but neither has access to the other.

I asked this question a little back and got some good responses, however I'm not sure about the details of what is going on.

If I plug one wireless router's WAN port into the modem and it gets a WAN address in the subnet then I put its LAN on the subnet then I plug the other wireless router's WAN port into one of the LAN ports on the first wireless router and let it get a WAN address in the subnet but I configure its LAN subnet to be will there be any communication between them? What will happen if someone on the subnet asks for an address on the subnet? Will it get to the first router and be routed to that subnet? Which router would be the guest and which one the work router?

Another option that I've thought of is to set up the modem as DHCP and connect it to a switch coming out of the modem. In that case each wireless router could get a WAN address on the subnet and have a LAN subnet in the address space. Is this a better configuration? What communication would there be between the two in this case?

Another question that I've had while trying to set this up is why the WAN port can't have the same subnet as the LAN on a wireless router. Why can the WAN port not have and the LAN subnet be in the same address space? This is sort of related to the previous question although not directly.

Thank you for any help you can give,
