I am installing a Cisco Ethernet Router 831 on a network to act as a gateway to the Internet. The internet is ADSL and terminates at a modem which is then connected via ethernet into the WAN link on the router (E1). There is a SMS2k server and about 15 workstations (XP/2k) on the network connected to an unmanaged 24 port switch. The switch is connected to (E0) an ethernet port on the router's built-in switch. The workstations and server can see the router but cannot see the Internet or the WAN link. Here is my configuration:

Any help would be highly appreciated, nothing I do seems to make a difference (adding acls, deleting them, static ip routes, router rip, NAT/PAT, etc).
Thanks in advance for any and all help regarding this matter.
