I have just got one of these and unsure how to configure it. I have 8 useable IPs from my ISP and behind the router will be a Cisco ASA 5505. One of my public IPs is configured on the external interface of the ASA. Therefore, what I want is for my 877 to be able to receive traffic for any of my public IPs, and then to route the traffic through to the ASA. I have tried this with SDM but cannot get it to work :(
