I can't say as to whether your second termination was fair or not. However, I know of cases where networks were compromised by exactly this means - using a privileged computer through a guest network, computer got trojaned, now there's something running on the inside of the privileged network, and bad stuff starts happening. Maybe the company overreacted by firing you, but it wasn't for trivial reasons.

You're not going to learn as from events if you fail to look at them openly. You absolutely need to look at events from the other side as well as your own, in order to grow. Sometimes you'll still decide that you were 100% in the right. But that's really rare.

Think about what you were doing. Why were you bypassing network policies? Why didn't you ask if you could do that? That's really the question to ask yourself - why didn't you feel like you could ask "hey, this policy makes no sense, can I, a smart person, do something else?"
