Simple routing using a Cisco 871

I have just got a Cisco 871 which I am configuring through "Cisco Configuration Professional" and IOS commands where needed, both of which I am familiar enough with the use of.

I am trying to set up a simple route configuration between two laptops with the router in-between, however I cannot get the router to route!  Using ping, no response.

Here's the set up:

Laptop 1 - IP: 10.156.1.99  Subnet Mask: 255.255.0.0 Default Gateway: 10.156.1.9

Router WAN interface - IP: 10.156.1.9  Subnet Mask: 255.255.0.0

Router VLAN Interface (Switched Port 3) - IP: 192.168.1.1  Subnet Mask: 255.255.255.0

Laptop 2 - IP: 192.168.1.2  Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.1

All other settings are factory default.  I've tried setting up various static routes but they don't seem to help.  As I said, I'm new to Cisco, any help would be appreciated.  

Many thanks,
Richard

Try this:

conf t
ip routing

Can each PC ping its gateway?

If still not working, can you post a "show run" from the rotuer?

Each PC can ping it's Gateway and other sides gateway, ie Laptop 1 can ping both 10.156.1.9 and 192.168.1.1, but not the other laptop.

Just a note, there are no other hardware or software firewalls active between the laptops.

The conf t and ip routing didn't help.

Yep, that worked.  Could you quickly explain why it worked though, thanks.

JFrederick29Commented:
Yeah, you have the Zone Based Firewall enabled on the WAN interface with no policy defined which means it will block all traffic to and from that interface.  Once you have a policy defined, you can enable the Firewall if desired.
