Re: NAT configuration for Cisco 1700 series router

You'll need something like the following:

interface Ethernet0

   description Inside interface

   ip address 10.1.1.1 255.255.255.0

   ip nat inside

interface Ethernet1

   description Outside/Internet interface

   ip address 200.200.200.1 255.255.255.0

   ip nat outside

ip nat inside source list 100 interface Ethernet1 overload

access-list 100 permit ip 10.1.1.0 0.0.0.255 any

Obviously your inside and outside IP addresses will be different, so just replace them as you need to in the examples above. This will have all your inside users on the 10.1.1.0 network share the same external IP address when they go out to the Internet.
