I have a Cisco 1721 with 2 ethernet WICs and I need to prevent traffic between 2 LANs

I have a Cisco 1721 with 2 ethernet WICs and I need create an ACL but i'm not sure what the syntax would be. Here are my interfaces:

Interface IP-Address OK? Method Status Protocol
FastEthernet0 192.168.1.1 YES NVRAM up up
Ethernet0 (public ip) YES NVRAM up up
Ethernet1 10.0.0.1 YES manual up up

FastEthernet0 and Ethernet1 are my local networks. Currently they are both able to get out to the internet, but I need to prevent communication between the two.

Thanks!

Sorry... I should have included the subnet lengths... the 10.0.0.1 network is a /16, and I'm pretty sure all that means is the 0.0.0.255 changes to a 0.0.255.255, right?

Also, Ethernet0 is my connection to the outside world. Would I not apply ACL 101 to Ethernet1 instead of Ethernet0?
