Re: Firewall configuration
A very long time ago - back before I had graduated Uni and my IT career had even begun, I was earning beer money doing evening & night-shifts at a Mobil petrol station across town.
During my day-time induction no-one had thought to show me how me how to turn the outside lights on when it got dark (I mean, obvious, right?) In hindsight, moving a big lever switch to the "Off" position was never going to be the correct choice. In my defence, I was young, stressed, feeling a little bit out of my depth, and the big switch was very compelling...
I had to wake my boss up at home (No idea why he was asleep - it can't have been later than 22:00), and he did a sterling job of stepping me through the site power-up process from memory. Apparently if I'd left it 5 more minutes before ringing him, the pumps would have lost their internal config and needed re-programming.
Somehow I kept my job - I even got a reputation for being one of the more reliable members of staff, which might go some way to explaining why you don't see Mobil around any more...
