i have a cisco 2800 series router with 2 lan port fe0/0 and fe0/1. i got an internet connection to fe0/0 with a private static IP of 192.168.1.30 from a linksys router on my network.
I connected a cable from fe0/1 to a switch to spread internet service giving it an IP of 192.168.0.1 but c an seems to get the internet connection spread through the router
In addition to adding the default gateway, I suspect that your Linksys router will need to learn of the 192.168.0.x network as well, otherwise when it receives a packet destined for 192.168.0.x, it won't know what to do with it (since it'll have no routing path to it) and it'll just send the packet to the default gateway (typically the WAN interface).
Most SOHO routers have the option for Advanced Routing, where you can add the route to 192.168.0.x.
The other option is to enable RIP on the Cisco router and the Linksys router. I actually did a similar experiment like this yesterday, and after troubleshooting for a while, I realized that the issue was with the lack of a route to the 192.168.0.x network on my Linksys router as well.

killabee is making sense, but sometimes on the same network I usually configure an XP box with two LAN cards to distribute internet service from 192.168.1.1 gateway to 192.168.0.0 network and it works without any special config on the linksys router.
i have also use the command IP ROUTE 0.0.0.0 0.0.0.0 192.168.1.1 but to no avail. tommorrow i will post my show run config
As has been said above you need a default route on the 2800 router that point to the linksys IP. And a static route to the 192.168.0.x network on the linksys that points back to the 2800 router IP (192.168.1.30).
May I add that you also need to make sure the NAT range configured on the linksys includes the 192.168.0.x range. This will make sure that the linksys applies NAT translations for the 192.168.0.x range.
