ok, copy and paste with  only minor munging

I can reach this machine from 178.x.x.x as normal. I can ssh in, and ping it

however, when I come from the ipv6 range, I can ssh in, but I can not ping it.

There are no other conditions in play on this remote machine, what you
see is what is there
So I dont get why when  _range_ ACCEPT works for all protocols on
ipv4, but it doesnt with ipv6
