Have a Netscreen that appears to be functioning correctly (it's in production and has been for several years), but yet is not allowing me into the Web interface on port 80 or 443 (also tried 8080). Tried telneting to 22 and 23 as well. Any attempt to connect times out. I've nmap'ed the IP on the internal interface and all ports show as being filtered, but as far as I recall, it was listening on 80. Also tried the external interface as it was setup for remote management, but can't connect that way either.
It was working last time I tried getting into it (last fall, I think).
I've cycled the power on it twice (pulled the adapter, waited 30 seconds, plugged it back in), but no dice.
