OK show me a lighting arrestor for Cat6(5e).

Simplicity itself. 1000 baseT to fiber. Run fiber between buildings,
then fiber to 1000 baseT. Hurts the wallet. Works. Don't use fiber that
has conductors bundled with it. In the case of a direct strike, you are
always screwed, but not putting conductors out there where they can
cause pickup helps, and the fiber link would at least keep the damage to
whichever building got struck. Of course, if you are connecting power
between the buildings, that can serve as a method for lightning pickup.

This guy actually knows what is going on. Fiber IS the ultimate
"creepage distance".
