Hi I've a quite simple question but I cannot find how to get out of it .
I've a cisco 1700 with an ADSL interface .
I need to configure the ethernet interface with private IP and assign the one of the assigned public ip to a loopback interface and have it natting the inside traffic .
below an extract of the configuration , which doesn't work
can anyone point me out where I'm wrong ?
thanks
