Hi there,

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

version 12.1
no service single-slot-reload-enable
no service pad
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
hostname router-dslgw
logging rate-limit console 10 except errors
enable password password
mmi polling-interval 60
mmi auto-configure
no mmi pvc
mmi snmp-timeout 180
