WRT54g connected to another router/bridge

[utoyo]

Got a WRT54g connected to a cable modem which acts as a router. The WRT54g gets an IP address (192.168.1.x) from the cable modem and the WRT54g can ping and tracert to sites on the internet (from the diagnostics page). The WRT54g is acting as a DHCP server for the 192.168.9.x network and I have the cable modem connected to the WAN port. (I need to have the cable modem connected to the WAN port b/c I'm using all the ports of the WRT54g. I want to have the cable modem connected to the wan port too so the network are separate subnets).

Any idea why packets would not be going through the WRT54g? I've tried setting the router and gateway modes, neither of which work anymore. I think I used to have it set to router and it work.

Any thoughts? Suggestions?

Thanks in Advance.
