I have two LinkSys Wireless-G routers straight from CompUSA.
I want to do the same thing in order to support some testing. I want a Router-01 to be my gateway DSL router with 192.168.1.0 as its LAN side subnet. Router-1 is 192.168.1.1 on its LAN side.
Router-2 is 192.168.2.1 on its LAN 192.168.2.0 subnet with its WAN connection is 192.168.1.5 in the first port of Router-1.
I have done the "Internet" accessibility thing successfully. My 192.168.2.0 clients use 192.168.2.1 as their "gateway". Thus, Router-2 passes their requests to Router-1 which is a "gateway" to the DSL cable modem. Subnet 2 clients can browse the web all day and they can access Subnet-1 machines with pings, etc.
What I cannot do is access Subnet-2 computers from Subnet-1?
Any time I try to change either Router-1 or Router-2 from a "Gateway" to a "Router" on the Advance Routing tab, it stops clients from accessing the internet or the next higher subnet. Any ideas?
