Cisco Router: Traffic U-turn on the interface

mrbzumrbzu · ‎08-04-2010

Hi All,

I have cisco router which has an internet interface having an external IP addres. I would like to redirect the traffic comming on IP lets say 1.1.1.1 to another IP 2.2.2.2 which exists on the internet as well. How i could achieve this on the cisco router?.

router recieves IP source (Any) destination (1.1.1.1) , i would like to forward back this traffic using same internet interface and change the destination IP to 2.2.2.2. your help in this case will be highly appriciated.

Regards

You will need to use NAT to do this.

This configuration is colloquially referred to as "NAT on a stick" (the 'stick' is the single interface)
