OK, we're actually talking about a couple of unrelated things.
"the normal screen pops up" Do you mean the password prompt or do you mean that you're taken directly to the setup page?
"when i go to status, it has login as disable" I never really noticed this before, but mine say the same thing even though I can login from inside the lan or outside the lan on any of them. I suspect this would only say enabled if you were using a DSL/cable service that requires login to the ISP such as PPTP or PPPoe. In any event, it is unrelated to your problem.
What firmware are you using on the router? Also, what browser & version are you trying to access it with? I suspect this is a password type problem.
