Can someone please educate me on what the settings should be when configuring a wireless router (hardwire to wan/dsl modem) behind a Bellsouth westell 6100 modem? As regards the IP addresses, gateway, subnet mask. The wireless router is handling the dhcp functionality of the lan. What I want is for the dsl modem/router to act only as a modem, and the wireless router behind it will handle the lan addressing and be the access point. I have been told that if the dsl modem/router has an IP address of 192.168.1.254 (which it is), the router behind it has to be in a different IP address range, like 192.168.2.4. How can I set this up so that the router IP address will be in the same range (192.168.1.xxx)? Also requesting that someone tell me how the default gateway, dns and subnet mask should be set on each unit. Should I turn off DHCP on the dsl modem/router? I thought that applied to the IP address assigned by the ISP server. Should I turn off NAT function in the dsl modem/router? What about IP passthrough; enable? The router mfgr tech support says the settings have to be made in the dsl modem/router, and the ISP says they have to be made in the wireless router. Should the gateway be the IP address of the wireless router or the dsl modem/router. I've been working on this for days and have to finish tomorrow. This is the last part that is giving me trouble.
