[Config] problem with 2841 and vlan with switch module

I'm trying to get this setup to work but am having issues.

Cisco 2841
Ethernet0/0 - 10MBit internet
External Ip address
Nat outside

VLAN2
Switch port 0/0/0 and 0/0/1 in trunk mode
nat inside

0/0/0 goes to a 10Mbit Timewarner ILAN connected to 3 offices

0/0/1 goes to the local network
ip address 10.0.0.3 255.255.0.0

route 0.0.0.0 0.0.0.0 external gateway

Inside the router EVERYTHING works. I can ping the internet from any router and all the addresses at the remote sides.

Problem is none of the workstations can see past the external address on the 2841.

You need to do the following;

1. Setup a standard access list that matches your workstations subnet

2. Attach that access-list to a IP SOURCE-LIST NAT statement

Thanks, a coworker told me the same thing. It was there but had the wrong subnet.
