No I'm not talking a small spark when you plug it in. I'm talking about
lightning hitting the wire during storms. It would arc off the wire when it
wasn't plugged into the arrestor.

The problem wasn't caused by the ethernet wiring; it was the difference
in ground potential between the two homes.

You should have optically isolated the two ends to avoid the problem.
