I am still learning the PIX501, but I've run into a situation that I am hoping someone can help explain.
When I setup a PIX from factory default settings using PDM, if I go to Configuration -> Interfaces and set the external interface to use PPPoE (which is what I use). A few seconds later, PDM shows the interface as active. If I go to Tools -> Ping and I ping an external address, it doesn't work by default. If I select "Outside" interface from the drop down list and try again, it works fine. Even though this is the case, I cannot get online with any computers inside of the network.
If I start using a PIX from factory default and I use the Startup Wizard, setting PPPoE in there, I immediately get access to the internet from all machines inside of my network. Also if I go to Tools -> Ping in PDM, I can ping an outside address fine without selecting the "Outside" interface specifically.
So, my question is, what is the Startup wizard doing extra that I am not. I hate relying on a wizard as I will be responsible for maintaining these in the future. Any thoughts or ideas that I could look into would be appreciated.
