Thanks to: http://jordansciscos.blogspot.com/ The scenario is that I have two Internet links. One over Ethernet and the other over ADSL. I want to push particular hosts on my internal LAN out through the ADSL and the others out through the Ethernet link. 192.168.0.0/24 = LAN Subnet FastEthernet0/0 = LAN Interface FastEthernet0/1 = Internet Connection 1 (Fibre/Cable) Dialer1 = Internet Connection 2 (ADSL) interface FastEthernet0/0 ip policy route-map PBR The above defines the internal LAN interface to be assigned to the "PBR" route-map which we will define below. ip nat inside ! ip nat inside source route-map ADSL-Only interface Dialer1 overload Specifies that all NAT must adhere to the ADSL-Only and LAN route-maps defined later ip nat inside source route-map LAN interface FastEthernet0/1 overload ! ip access-list extended ADSL-Only My two hosts that I want to go out over ADSL permit ip host 192.168.0.15 any permit ip host 192.168.0.10 any ! ip a
