    My ISP issued me a new modem/router and the LAN side is 192.168.1.1 and the Linksys router that I need for port forwarding is also the 192.168.1.1 series. Is there a way to use the Linksys router with the modem router? The modem router is an ADSL that has the encapsulation settings and the ISP's specific settings in it. It is a lot different than any of the AT&T modems that I have used. The ISP is a small company that is protected from the AT&Ts of the country, so it's their way or no way. Any help is appreciated! Alan

    Basically three choices, in no particular order ...

    a. "Bridge" the modem/router to make it operate as a modem only. If you have (A)DSL this will probably mean that you have to configure the WAN section of the Linksys for PPPoE and your account/password.

    b. Change the IP subset for the LAN on one router (e.g., to 192.168.3.x).

    c. JohnWill's procedure (Aug. 30, 2008) for configuring a secondary router as a switch and, optionally, wireless access point follows.

    Connecting two (or more) SOHO broadband routers together.

    Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

    Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

    Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

    Disable the DHCP server in the secondary router.

    Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

    Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. [You will not need a cross-over cable if one of the "routers" is a computer.] Leave the WAN port unconnected!

    This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

    For reference, here's a link to a Typical example config using a Netgear router

    Wanna make sure you understand those are three different ways to go.

    You're welcome.
