Gateway of Last resort
Posted on 2007-11-23
I am trying a basic set-up that I want to look like this:
ISP router (cisco 870)
My ISP has given me a /29 network of public IP addresses, the first address is assigned to the ISP's router. I have assigned the second in the range to the Outside interface of my ASA. I am planning to use the rest of the IPs in a DMZ and for some NATting. The problem is that when I try to specify the default route to be the IP of the ISP's router, I get warned that the route is directly connected, which it is.
But how do I specify my gateway of last resort to use the ISP router?
