This was working and all of the sudden it stopped.  I believe the tunnel still may work but because it can't connect to the Internet, I can't test.  Can anyone help?

There's your problem... You don't have an IP address (or a default route).

I would either bounce the interface (shut it down and then bring it back up) or remove the IP address assignment and reapply it.

Commented:
FastEthernet 4 is connected to the Internet (ISP) so it's getting it's IP dynamically (don't know what it is).  So would I just do a command to send all traffic to FastEthernet 4?  Is there a way to see what the IP is on the WAN interface that it is getting from the ISP?

Yes. "show ip int brief"

Yours shows:
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet4             unassigned      YES DHCP   up                    up

Author

Commented:
Still showing as unassigned...Does that mean it's just not getting an IP from the ISP?  Did a shutdown on the interface and brought it back up...

Correct.  

Since the interface is showing UP/UP, it would appear that you have a connection.  You're just not getting a reply from their DHCP server. So I would contact the ISP.
