I have a cisco 1800 router. I have a ethernet connection from the ISP. I have their ethernet connection with 1 routable ip applied to fe0/0 and 16 routable ips applied to fe0/1.
My firewall is connected to fe0/1. I need all 16 routable ips available on the internet. I have it working with a linksys router in router mode vs gateway mode but I figure I should be able to use this enterprise cisco router instead.
