I have configured my Cisco 827 with the following configuration but cannot get it to work, I have spent days and tried absolutely everything to get this to work and trawled the net for examples but still no joy.
Could someone please take a look and see if they can see where I am going wrong. The config is a completely NO NAT config, the router has an external ip address (same IP address on the WAN and the ethernet) and simply forwards all traffic to my firewall (again on an external ip address).
Here is the config
