Cisco 1921 not passing traffic

Question:

I'm fairly new to Cisco 3945 router Cisco routing, and I'm a bit lost on this issue.  I have a 1921 that is going to be a WAN router for a fiber Internet connection.  It will sit in front of the network firewall and needs to route all traffic to the Internet.  I thought I had the config set right with a default route of '0.0.0.0 0.0.0.0 <wan gateway>' but it doesn't seem to be working.  Config is below.
The router can ping from itself to hosts on both sides and hosts on the Internet with no problem, but a laptop connected to the "LAN" side and assigned a public IP address can ping both sides of the router but no further.
I've done a bit of searching on the forums but every similar issue I've found seems to involve NAT - I have another device doing NAT so I don't want to do NAT on this router (traffic needs to be able to reach the public IP addresses on the "LAN" side).

Answer:

can you add auto mdix to the wan interface?

also can you check which kind of cable is connecting the 1941 to the ciena switch and reloading your router too? Cisco 3945 price
