Though I do not have an in-depth knowledge in loopback interface. I would
like to add on a bit of my experience working on it.
I have tried to configure a loopback interface for NAT kind of config (For
Internet access ) with the interface as ip nat outside. It did not work.
Eventually, I have to remove it and put the nat outside statement into my
E0.(E1 is my ip nat inside)Surprising that works!!
I was told that loopback interface is only for intranet configuration. Is
this really true, I am not so sure?? :) Well that's was my experience....
