number your internal lan addresses in a different subnet. Use 192.168.2.x for your lan. Then, because the modem is on a different subnet, it should "just work". At least in my lan it works that way. My dsl modem is accessible as 192.168.0.1 while my lan is 192.168.1.x.

also, you can sometimes (depending on how its all configured) access the modem by browsing to your *public ip* which resolves to your modem, but since you're coming form the inside, it gives you the configuration.
